Error description
A CICS region shows storage accumulating in UDSA due to EIQSKBUF storage. This storage is acquired by module DFHEIQSK while processing an EXEC CICS INQUIRE TASK IPFACILITIES IPFLISTSIZE command. This storage is used as a buffer for the IPFACILITIES list. . A GLUE program running at exit point XPCREQ is issuing the INQUIRE TASK request. The storage accumulates for long-running tasks and eventually CICS goes SOS. For other tasks, the EIQSKBUF storage is freed at task termination. . Additional Symptom(s) Search Keyword(s): KIXREVxxx INQUIRE-TASK GETMAIN_IPFACILS_BUFFER

Problem summary
**************************************************************** * USERS AFFECTED: All CICS Users. * **************************************************************** * PROBLEM DESCRIPTION: Possible SOS condition when issuing * * EXEC CICS INQUIRE IPFACILITY. * **************************************************************** It is possible for CICS to suffer a SOS ( Short on Storage ) condition when a GLUE ( Global User Exit ) has been written which issues the EXEC CICS INQUIRE IPFACILITY command. The SOS may occur in the UDSA should the task running the GLUE be long running. In this case an EIQSKBUF is getmained to hold the data returned from the INQUIRE IPFACILITY call, but not freed. It would be freed if this transaction terminated. The next time the GLUE is driven it will acquire another EIQSKBUF of x'28' bytes.
Problem conclusion
Temporary fix
Comments
DFHUEH has been changed to free the EIQSKBUF after the GLUE returns control to CICS.
