Have you had a try with valgrind? http://valgrind.org/docs/manual/quick-start.html
I'm not having any gearman environment myself.
Have you talked to the mod_gearman guys? https://mod-gearman.org/support.html

mod_gearman is an external addon which we do not maintain. Memory leaks introduced by NEB modules cannot be avoided by the core itself, so I suggest to contact the addon developer about this possible leak.

I meant - which mod_gearman-like-application do you suggest to use? is there addon which supports icinga like mod_gearman supports nagios?

P.S icinga 1.14.0 has the same problems with last stable mod_gearman

mod_gearman is an external addon for Nagios/Icinga. Generally speaking, if you add any NEB module onto the core and it does not take care about proper memory handling, it may introduce memory leaks. Icinga Core itself as tested and released by us, does not introduce any.
Icinga 1.x itself doesn't provide any NEB modules, except for the IDOUtils module for the database backend. As said, I'd suggest to contact the mod_gearman developer and ask about possible leaks with specific functions. I don't have any test setup with mod_gearman around, and won't be of assistance here.
Kind regards, Michael

Hello there! We have the memory leak with icinga-core 1.13.3 via mod_gearman 1.5.5 (libgearman 1.1.8) [root@icinga icinga-1.13.3]# pmap - x 55072 | head 55072: /usr/local/icinga/bin/icinga - d /usr/local/icinga/etc/icinga.cfg Address Kbytes RSS Dirty Mode Mapping 0000000000400000 664 360 0 r-x-- icinga 00000000006a6000 4 4 4 rw--- icinga 00000000006a7000 44 44 44 rw--- [ anon ] 0000000001e5b000 68344 68296 68296 rw--- [ anon ] 0000000006119000 1756 1724 1724 rw--- [ anon ] 00007faa8c000000 132 4 4 rw--- [ anon ] 00007faa8c021000 65404 0 0 ----- [ anon ] 00007faa94000000 512 248 248 rw--- [ anon ]
In the String: 0000000001e5b000 68344 68296 68296 rw--- [ anon ] column Dirty is growing up and isn't falling down i.e. we are watching memory leak of icinga working with mod_gearman module. This module starts up via broker (not via own config but via string broker_module=/usr/local/icinga/lib/mod_gearman/mod_gearman.o config=/etc/mod_gearman/mod_gearman_neb.conf in icinga.cfg )
Just to clarify we already have the variant with the latest version of headers.
