EXCI pipe limit exceeded
A problem with error ECI_ERR_SYSTEM_ERROR can occur if
the EXCI pipe limit is exceeded during communication between CICS
servers. This is due to an MVS system pipe limit.
Pipe limit exceeded for available sessions
A failure with error CTG6882E can occur if
CICS Transaction Gateway tries to allocate more pipes than the number
of available sessions defined in the CICS sessions definition. This
is due to a CICS Transaction Gateway system pipe limit.
