you can see here a 22165 allocations for 240 bytes, that was not released
(other are not so significant, but can be the same trouble).
and their count is constantly growing.

what else can i provide to find out a place of leak?

ps: valgrind is not an options, due to very huge slowdown. i've tried it.
:(
