****************************************************************
In a highly stressed system, occasionally, the scheduler
can not obtain the admin client.  This triggers a
NullPointerException when the caller attempts to use the admin
client.

Problem conclusion

The scheduler will cache the admin client object for each peer
scheduler.  The fix for this APAR is currently targeted for
inclusion in fixpack 8.0.0.4 Please refer to the Recommended
Updates page for delivery information:
