[Freeswitch-users] unexplained RAM usage increase

Wed Jan 30 03:40:46 MSK 2013

Anthony, I tried bisect and the problem is that there are other issues (RTP error still in 1.2 stable, waiting for 1.2.6), and about 4-5 other issues in head that prevented it from working for a good amount of time. I started jiras for them and they are fixed, but doing bisect brings them back so it's had been really hard to pinpoint the memory issue. Believe me, I have put a LOT of time into trying to narrow it down before opening a JIRA and will continue to do so. Right now it's hard since there were personal emergencies the last 2 months so other pressing things had to take priority. Still, I am working on FreeSwitch keeping up-to-date with head in case other issues pop up I can open a JIRA on them.

I had to triple memory and recycle FreeSwitch every 2-3 days since then. Will open a Jira when I can obtain detailed info and possibly run valgrind. I am also also waiting to update the main FS computer from 10.6.8 to 10.8.3 to see its effect. Hopefully in Feb.
