The most common problem is the CCI Logger databases is fragmented. A REORG will clear this up. It is best to do this on a regular basis, maybe even daily. Changing the Logger parm to a Y will REORG the database every time it is restarted.
Y or N. If Y is specified, LOGGER reorganizes the VSAM database at CCILGR startup.
If this is a regular process, then you may have another problem. Check your z/OS LOGREC file for hardware errors. If nothing hits there, send the dump in to Common Services support for review.
