GTZ0004E

Explanation
The IBM® Generic
Tracker for z/OS® is running
out of storage. Most likely a large number of tracked instances has
accumulated.

System action
The IBM Generic
Tracker for z/OS will continue
to run, but with limited function until some tracker owned dynamic
storage has been released again.

Operator response
Contact your system programmer.

System programmer response
The system might release tracker owned
dynamic storage automatically after peaks of activity during which
dynamic storage is used for temporary objects. 
Try the DISPLAY
GTZ,STATUS operator command to see if the tracking facility MEMORY
usage is still marked as full.
If this condition persists:
Consider using the SETGTZ CLEAR command to release dynamic storage.
Clearing TRACKDATA is typically the most effective way to regain storage.
Consider inspecting your exclusion list. Your system might be
tracking known tracked instances. Compare the SETGTZ EXCLUDE command
and the GTZPRM00 parmlib member.
Consider specifying a higher maxmimum size for tracker owned dynamic
storage. Compare the MEMLIMIT parameter in the GTZ procedure which
is used to start the tracking facility.
