Unable to find terminal entry (session id , terminal index , terminal id )
The Client was unable to locate an internal control structure associated with a terminal or EPI program. This may occur if an ATI request is received for a terminal that no longer exists because either the Client or the terminal was shut while the ATI was in transit.
The message is written to the error log and Client processing continues but the emulator may be unable to continue.
If the problem persists, contact your service organization.
