As yesterday was a day off here in Belgium (Whit Monday), I just picked up this Red Alert today. The contents of this Red Alert :

In z/OS 1.9 GRS recovery for GQSCAN retries with incorrect registers. 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 (...)'.
