This can result in an ABEND0A0 followed by repetitive ABEND0C6 or ABEND0C4 in ISGQNX. As a result of the program check loop in ISGQNX's recovery no GRS work is able to run on the failing system. This may cause sysplex-wide impact for the following reasons: - Global resources held by the failing system cannot be released causing tasks that request the resources on other systems to wait. - If the failing system is a GRS Lock Manager, other systems may not be able to complete their XES requests. - Global GQSCANs may time out. - Global TEST ENQs cannot be processed. - No list ENQ requests can be processed on other systems if the failing system is holding the GRS list lock. Symptoms may also include: - High CPU usage in GRS and *MASTER* on the failing system. - Message ISG361I indicating delays on other systems in the Sysplex. - D GRS, C is unable to complete on the problem system and Message ISG343I only returns local resource data on other systems.
