*** ORIGINAL QUESTION ****
Does anybody know what this means? It's a Solaris 2.5 system running sendmail
8.8.3
This is from /var/log/syslog
Nov 20 10:02:12 condor sendmail[17000]: proc_list_probe: lost pid 10116
Nov 20 10:02:12 condor sendmail[17000]: proc_list_probe: lost pid 10271
Nov 20 10:02:12 condor sendmail[17000]: proc_list_probe: lost pid 10479
*** ANSWERS ****
I forgot to mention sendmail was still running correctly even though reporting
this problem. I've installed it on 2 other solaris 2.5 machines but this is the
only one reporting this problem.

Yes. It's a bug in 8.8.3 I found this in comp.mail.sendmail yesterday --
haven't had a chance to install and test it yet.

Seems to be related to this:
Improvements to MaxDaemonChildren code. If you think you have too
many children, probe the ones you have to verify that they
are still around. Suggested by Jared Mauch of CICnet, Inc.
Also, do this probe before growing the vector of children
pids; this previously caused the vector to grow indefinitely
due to a race condition. Problem reported by Kyle Jones of
UUNET.
Thanks again!!
