[SR-Users] kamailio very slow or stuck during period from time to time

I am using a 4.3.3 version built myself from source.
(deb package were not released at that time)
I am expecting a few hundred connections.
(core.tcp_info or netstat )
Finally I have removed this line:
modparam("usrloc", "close_expired_tcp", 1)
It seems it was causing the memory leak.
I am still monitoring everything.
