The server attempted to generate a default ARM element identifier to use for automatic restart registration, using the one or two character &SYSCLONE value to identify the MVS system. Normally, MVS verifies during start-up that &SYSCLONE is unique within the sysplex. However, the server is running on a level of MVS where this check is optional and has not been performed, so the server is unable to generate a unique element identifier.
The server is terminated.
Servers should not normally be run on a level of MVS which does not enforce unique &SYSCLONE values. However, the problem can be bypassed by specifying an ARM element name explicitly on the server ARMELEMENT parameter.

A queue server STOP command has been issued (either via an MVS STOP command or via an MVS MODIFY command with the text STOP) but there are still active connections to the server, so the STOP command has not yet taken effect.
The server rejects any further attempts to establish new connections, but continues processing requests for existing connections. Each time a connection is terminated, this message is repeated for as long as there are more active connections.
Further information about the connections which are still active can be obtained using the command DISPLAY CONNECTIONS.
If the server needs to be shut down without waiting for connections to be closed, issue the queue server CANCEL command. Note that this immediately terminates any active connections, causing any further requests for that server to be given a SYSIDERR indication. (The MVS CANCEL command can also be used, but should preferably be avoided because it prevents the server from producing its normal closedown statistics and reports).
Note that if a CICS region is abnormally terminated while server connect or disconnect processing is in progress, or is terminated without going through end of task processing (for example using the FORCE command) there is a slight chance that the server will not be notified that the connection has been terminated. In this case the server is not able to be closed down with the server STOP command, but only with the server CANCEL command.

If the reason code is known to the server, the name of the reason code is given (without the ConaRsn prefix), otherwise its decimal value is shown.
If the response indicates InvalidStructureSize, this means that the initial list structure size (specified on the server POOLSIZE parameter or in the CFRM policy INITSIZE parameter) is not large enough to contain the required structure control information. The size of the control information is affected by the number of list headers (determined by the server MAXQUEUES parameter) and by the maximum structure size specified in the CFRM policy.

See the descriptions of the reason codes in the MVS macro IXLYCONA which maps the connect answer area.
If the response was InvalidStructureSize, increase the initial structure size specification in the server POOLSIZE parameter or the CFRM policy INITSIZE parameter to ensure that there is enough space for data in addition to the structure control information.

This message is issued by the queue server when the percentage of list entries in use within the list structure increases past certain set threshold levels, or when it decreases past a threshold level after previously being at a higher level. This message is also issued immediately after an ALTER request has completed in order to show how the percentage has been affected by changes in the structure size or entry to element ratio.
The warning threshold is increased to the next higher level (normally 5% higher if less than 95%, otherwise 1% higher), or decreased to the previous lower level depending on whether the usage is increasing or decreasing. If the structure usage is increasing and the structure element to entry ratio is not making full use of the available space, the server may issue an automatic IXLALTER request to adjust the ratio.
Note that the structure may soon become full, preventing queues from being created. If the structure was allocated at less than its maximum size and the coupling facility has enough free space, the size of the structure can be altered dynamically using the MVS SETXCF command with the START,ALTER options.

A return code of 8 indicates that the MVS STIMERM macro failed, in which case the reason code indicates the return code received from STIMERM CANCEL.

The queue server statistics collection subtask was unable to continue processing and has terminated. The reason will have been indicated by an earlier message.
The interval statistics subtask terminates and no further interval statistics or end of day statistics will be produced for this run of the server.
See the earlier message indicating the reason for the termination of the subtask.

Queue server statistics have been sent to SMF. The return code from the SMFEWTM macro is indicated in this message. A non-zero return code usually indicates that SMF recording was suppressed because of current SMF options or an installation exit.
Processing continues.
If the return code is non-zero but SMF statistics were expected to be successfully written, see the SMFEWTM macro in MVS/ESA System Management Facilities (SMF) (GC28-1457) for more information about return codes.

The data set to contain the unloaded queue pool could not be opened.
Unload processing is terminated and the server is closed down with message DFHXQ0706.
Check that the DFHXQUL DD statement is present in the JCL for the unload job.
Console and SYSPRINT
DFHXQUL
The unload process failed because of a problem with coupling facility access.
Unload processing is terminated and the server is closed down with message DFHXQ0706.
If the response code is 8, this indicates that an unexpected IXLLIST error occurred, for which a previous error message will have been issued. Any other response code indicates an internal logic error.
Console and SYSPRINT

The queue pool unload process failed. The reason will have been described in a previous message.
The server is terminated.
See the previous message giving the reason for the unload failure. Note that any unload data set produced in this case will be incomplete and will not be valid for reload purposes.

The server program has been started with the RELOAD option requesting that the queue pool is to be reloaded from a sequential data set produced using the UNLOAD option.
The server starts to process the reload request. In this case, the rest of cross-memory server initialization is bypassed as it will not be needed.
None.

This message provides additional information about the results of the reload process. Queues on the unloaded data set are bypassed during reload processing if they already exist in the pool (for example as a result of a previous reload which could not be completed due to lack of space).
Server termination processing continues.
None.
Console and SYSPRINT

The data set containing the queue pool to be reloaded could not be opened.
Reload processing is terminated and the server is closed down with message DFHXQ0808.
Check that the DFHXQRL DD statement is present in the JCL for the reload job.
Console and SYSPRINT
DFHXQRL
The reload process failed because of a problem with coupling facility access.
Reload processing is terminated and the server is closed down with message DFHXQ0808.
If the response code is 8, this indicates that an unexpected IXLLIST error occurred, for which a previous message DFHXQ0441 will have been issued. Any other response code indicates an internal logic error.
Console and SYSPRINT
DFHXQRL
End of file was encountered on the unloaded data set before the logical end of the unloaded data was encountered.
Reload processing is terminated and the server is closed down with message DFHXQ0808.
This indicates that the unloaded data set is incomplete, perhaps because the unload process was abnormally terminated.
Console and SYSPRINT
DFHXQRL
The reload process failed because the unloaded queue pool data set is not in the correct format.
Reload processing is terminated and the server is closed down with message DFHXQ0808.
Check that the correct data set is being used and that the unload process completed normally.
Console and SYSPRINT
DFHXQRL
The queue pool reload process could not be completed. The reason will have been described in a previous message.
The program is terminated.
See the previous message giving the reason for the reload failure.
Console and SYSPRINT
DFHXQRL
Reload processing failed because there are insufficient free entries or elements to store the new data in the structure.
Reload processing is terminated and the server is closed down with message DFHXQ0808.
If the structure is not at its maximum size, use the MVS SETXCF FORCE to delete the structure, then change the reload parameters to specify a larger POOLSIZE parameter and rerun the reload job. The approximate amount of information which could not be reloaded can be estimated by comparing the numbers of blocks read and queues reloaded, as described by following message DFHXQ0803, with the corresponding numbers from message DFHXQ0703 in the unload job.
Console and SYSPRINT
DFHXQRL
Reload processing failed because all list headers defined in the structure are now in use.
Reload processing is terminated and the server is closed down with message DFHXQ0808.
Use the MVS SETXCF FORCE to delete the structure, then change the reload MAXQUEUES parameter to a large value and rerun the reload job.
