Hi all,
i am upgrading our nagios 1.2 (on freebsd 5.3-release) to nagios 2.0
(currently last cvs after 2.0b3) on Freebsd-5.4RC3 and i saw a very
strange thing.
After few hours, nagios main process (nagios -d ...) use lot of cpu time
and when i do a truss on the pid, i have a "kse_release" loop message.
# top

I know there is a pthread_acquire() issue with Nagios and FreeBSD
threads, but is there any patch against this ?
Thanks in advance...
