Re: [Nagios-devel] nagios 3 host checks logic problem on some=20
kernels/distros
Dear List=20
today I installed the new CVS to get rid of the host check logic problem=20
and the high cpu load.=20
I can confirm that load is in a normal range now but after installing CVS=
=20
someting with host- and servicechecks went terribly wrong.=20
Many checks return a critical result even if the checked system or service=
=20
is up. (I compared with a second nagios server running 2.9. Everything was=
=20
ok there.)=20
I executed the checkcommands manual from the commandline and received=20
correct values and an OK state, while Nagios said it is critical.=20
Caused by this I switched back to nagios 3.0b3. All services and hosts=20
returned to a normal state but of course CPU load is high again now.=20
Best regards=20
