Error description
CICS tasks are deadlocked. A task waiting on the TDEPLOCK lock is force purged. It seems there may be a problem with the task_purged routine in Transient Data which runs when a task waiting on TDEPLOCK gets purged (FORCEPURGED). TASK_PURGED routine tries to remove itself from the chain of waiters. However, if it just got promoted to lock owner in parallel with a FORCEPURGE, it won't be on the waiters list. There is nothing in TASK_PURGED which deals with the purged task being the new lock owner. This is a very tight timing issue. Additional Symptom(s) Search Keyword(s): KIXREVRJL
