Hi Michael,

There are other neb modules which bypass these limitations (mod_gearman,
dnx) by merging the checkresult list in memory, but that a) is not
thread safe b) could cause problems with large lists and a dead not

which daemon do you mean? Icinga? gearmand?
Icinga. Look for the code regions where the checkresult_list is touched.
You may adjust the reaper to "reap check results in batches", as there
could be certain conditions where the list in memory gets too long, and
the entire reaper time (stopped by a timeout, configurable in
icinga.cfg) is iterating over that list, but not even processing the items.
https://github.com/Icinga/icinga-core/blob/master/base/utils.c#L2773
(mod_gearman circumvents that if condition as it injects the items
directly into memory, not using that function. that's dangerous but our
calls were ignored.)
In the end you'll figure why Icinga 2 was born.
Consider a migration Btw - any chance for becoming an official
Icinga User? https://www.icinga.org/community/icinga-users/
we'll talk about that...
:-)
Kind regards,
Michael
