Local fix
Problem summary
**************************************************************** * USERS AFFECTED: * * All users of the IBM Communications Server for z/OS Version * * 2 Releases 1 and 2: OSA-Express QDIO interface * **************************************************************** * PROBLEM DESCRIPTION: * * zOS system (LPAR) outage with a system wait state code of * * 08F * **************************************************************** * RECOMMENDATION: * * apply PTF * **************************************************************** ISTLLCIE is operating (on CPU A) in disabled mode while holding a private spin lock while attempting to schedule another SRB for storage pool expansion. Another instance of ISTLLCIE needs to obtain this same spin lock but continues to spin (on CPU B) until the initial thread (CPU A) holding this private spin lock releases the lock. Due to other system recovery actions, the release of this spin lock (by thread on CPU A) did not occur before the system wait state is detected.
Problem conclusion
Reduce the code path for which this spin lock is being held. Do not attempt to schedule a new SRB to expand the buffer pool while holding the spin lock and operating disabled.
