Error description
The free QPF chain for the ICE subpool has become corrupt. The first byte of the first word of a cell on the free chain has been incremented, so that this cell no longer points to the SCA. The storage violation trap is active, and storage violations have been detected for a task who primary facility is an ICE. Additional symptoms: You are running with the storage violation trap- csfe debug,chkstsk=current and it springs. Later you may see the following: DFHSM0002 A severe error (code X'030D') has occurred in module DFHSMGF. This is occurring on subpool APICE31. Similar to PI45278, in that case the storage violation trap was no active. ICE QPF Invalid FREE cell

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users * **************************************************************** * PROBLEM DESCRIPTION: Storage corruption when Storage * * Violation Checking detects a violation * * caused by a non-terminal task. * **************************************************************** * RECOMMENDATION: . * **************************************************************** A CICS region is running with CHKSTSK Storage Violation checking active. A non-terminal task suffers a violation. Storage Manager calls DFHTFIQ to increment a counter in TCTTESCV, but the task does not have a TCTTE and has an ICE, so a piece of storage beyond the ICE is updated.
Problem conclusion
DFHSMCK has been changed to prevent it from calling DFHTFIQ when the task's principal facility is not a TCTTE.
