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-5.4RC2 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 (like a strace on linux), i have a
'kse_release' loop message.



# top
last pid: 75729;  load averages:  1.81,  2.08,  2.03
63 processes:  2 running, 61 sleeping
CPU states: 12.5% user,  0.0% nice, 16.0% system,  0.0% interrupt, 71.5% idle
Mem: 36M Active, 1639M Inact, 219M Wired, 68M Cache, 112M Buf, 44M Free
Swap: 5000M Total, 52K Used, 5000M Free

  PID USERNAME PRI NICE   SIZE    RES STATE  C   TIME   WCPU    CPU COMMAND

# truss -p 40435
kse_release(0xbfbf9b70)                          ERR#22 'Invalid argument'

kse_release(0xbfbf9b70)                          ERR#22 'Invalid argument'

What does it means ? i know that there are some issue with pthreads on
FreeBSD, but is it the same problem ?

Thanks in advance...
