Great, I'll use it in the standby server and will test with SIPp in order to determine the possible memory leak. > In this way, a restart does not print pkg and shm status, so it is fast.

For this purpose I've created a bash script which does the job for me :) I attach it. In the production server (no mem debugging compiled) I've created a cron job which invokes the attached script every 5 minutes. Then with other scritp I filter the PKG status from kamailio log file (rsyslog logs it to a separate file) and get this output: Apr 8 13:55:01 kamailio[11770]: used= 190936, used+overhead=250696, free=16526520 Apr 8 13:55:01 kamailio[11770]: max used (+overhead)= 258464 Apr 8 13:55:01 kamailio[11758]: used= 191176, used+overhead=250648, free=16526568 Apr 8 13:55:01 kamailio[11758]: max used (+overhead)= 257864 Apr 8 14:05:01 kamailio[11770]: used= 190936, used+overhead=250696, free=16526520 Apr 8 14:05:01 kamailio[11770]: max used (+overhead)= 258464 Apr 8 14:05:01 kamailio[11758]: used= 191176, used+overhead=250648, free=16526568 Apr 8 14:05:01 kamailio[11758]: max used (+overhead)= 257864 I cannot determine the memory leak cause with this, but I can determine that some memory exists if the 'used' value is increased, right?
