Yielding timeslice

[Troels Arvin]

Hello,

I'm getting a large number of paragraphs like this in a db2diag.log:

2008-10-22-09.31.50.339542 +120 I277626395A468 LEVEL: Warning

DB2 version: 8.1 FP 17 64 bit on AIX 5.3.

What does the message mean?

Hi Troels,

This message is likely benign - it doesn't indicate anything is wrong
with the system. My guess is that you likely have a large number of
agents (maxagents) and/or pooled agents (num_poolagents ) configured,
causing some contention on an internal serialization mechanism. If
this message is causing problems (db2diag.log consuming way too much
disk space because of this message), you should open a PMR or contact
your service rep to have this message removed (it's been removed in
v9.5, but that probably won't help you much :-) ).

Cheers,
Liam.
