no, that doesn't make much sense for core 1.x not being multithreaded at all. it obviously looks like that your core generates a lot of checkresults in a short couple of time, and therefore the checkresult reaper cannot process them that fast. it also sounds like that the in-memory list of checkresults has grown huge and takes ages to be processed. afterall it would be interesting in which interval the 5000 service checks are being run, and how long their execution time is. some icingastats and system performance graphing over time would help as well for the reader. https://wiki.icinga.org/display/howtos/Icinga+performance+analysis https://wiki.icinga.org/display/howtos/Optimize+Icinga+Performance -- DI (FH) Michael Friedrich mail: michael.friedr...@gmail.com twitter: https://twitter.com/dnsmichi jabber: dnsmi...@jabber.ccc.de irc: irc.freenode.net/icinga dnsmichi icinga open source monitoring position: lead core developer url: https://www.icinga.org ------------------------------------------------------------------------------ Android is increasing in popularity, but the open development platform that developers love is also attractive to malware creators.
