Environment

Common Services 14.1 & 15.0 - z/OS supported releases -  

 

Cause

A U600 abend in CCI means an internal CCI Resource pool has been exhausted, this is a GLOBAL pool.

Any task looking for a resource when it has been exhausted would encounter this abend.  

Resolution

The WLM service class for the address space holding the resources should be increased to prevent this from occurring. 

This is a diagnostic dump only.  CCI will continue to process normally once the problem is cleared.
