The abend U2999-1007 represents that a CA Health Check that was running in the SYSVIEW
user address space was executing longer than a defined limit.
If this occurs, then SYSVIEW will abend the Health Check to prevent the Health Check
from using an unreasonable amount of resources. This could prevent a looping Health Check
or a lock on resources for a long period of time. It it a safety mechanism to prevent
further system problems.
By default, the maximum amount of time a Health Check is allowed to run is 60 seconds.
If a Health Check exceeds 60 seconds, then it will be abended.
For reference, the timeout can be controlled in the GSVHHCHK parmlib member on the
ELPLIM 00:01:00 <----- This parameter.
Before to change the value defined in the ELPLIM we would recommend to review the service
class both the SYSVIEW main and SYSVIEW user address spaces are participating in and
consider allowing SYSVIEW to participate in a class that will allow them more service,
we typically recommend SYSSTC.
