Nagios Support Forum

I'm running Nagios CVS HEAD on 2.4.24-1-386 (a Debian kernel).
For now, I have only enabled one service (ping) to the
localhost. Unfortunately, this check stays forever in
the "pending" state.

So I turned on debugging and did some "ps" to dig around. What I
found so far is:


- files get's created
in /usr/src/nagios/dist/var/spool/checkresults. So far I have 6
files there.



- the normal nagios log says

[1200311267] Warning: The check of service 'PING' on
host 'lin01' looks like it was orphaned (results never came
back). I'm scheduling an immediate check of the service...

[1200311507] Warning: The check of host 'lin01' looks like it
was orphaned (results never came back). I'm scheduling an
immediate check of the host...



- Something doesn't work with signals. The longer I run nagios,
the more nagios processes hanging in rt_sigsuspend exist.
Right now I have those:

# ps -eo pid,comm,wchan|grep nagios
21307 nagios nanosleep
21308 nagios poll
21309 nagios select
21310 nagios rt_sigsuspend
21378 nagios rt_sigsuspend
21411 nagios rt_sigsuspend
21505 nagios rt_sigsuspend
21574 nagios rt_sigsuspend
21611 nagios rt_sigsuspend
21649 nagios rt_sigsuspend


Right now, upgrading this server to Kernel 2.6.xxx isn't an
option (because of the other services running on this box, which
I don't want to interrupt).

Any ideas?
