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 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 40435 nagios 112 0 4688K 3544K CPU0 0 569:46 93.99% 93.99% nagios [...] # truss -p 40435 kse_release(0xbfbf9b70) ERR#22 "Invalid argument" kse_release(0xbfbf9b70) ERR#22 "Invalid argument" kse_release(0xbfbf9b70) ERR#22 "Invalid argument" [...] I know there is a pthread_acquire() issue with Nagios and FreeBSD threads, but is there any patch against this ? Thanks in advance...
