If memory is the problem, and not CPU Load, try lowering the service_reaper_frequency. By default it is set to 10, which means every 10 seconds, Nagios will remove the contents of the pipe (what ALL the plugins write to - there is only 1 pipe) and process them. If you have that many services, you might be overwriting the pipe. I had similar problems on one of my systems where the box kept swapping all the time (about 750 service checks, most every 5 minutes). If you try lowering that value (try 5 for starters), Nagios will read the pipe more frequently, so it shouldn't get overwritten as much. Just another suggestion. -Russell Scibetti Shane_Seidel@gwf.com.au wrote: > > > >Hi All, > >We have a dual P3-1200mhz 512M RAM server running Nagios 1.0 monitoring 180 >devices and 800 services. > >I have noticed that the number of nagios processes increase until they reach a >count of approx 1000 at which time the server complains it is "out of memory" >and starts shutting down services. > >I found that executing '/etc/rc.d/init.d/nagios reload' from cron would "solve" >the problem.
