[Freeswitch-users] memory leak

Wed Jul 13 20:59:44 MSD 2011

I had a similar issue with commit 9cf44f3a5ee7cba9fc378447780499d41c4de671
of 6 July with a memory increase rate of 2Gb/day but now I have done a
revert to an old commit (2246f3ca75eee93a7e7f4409aa816513b99e657a) for a
reason not related to the memory leak.
For this reason I have not yet open a jira.
Due to a feature released recently, I'll do a git pull in next hours so I'll
share the info I have.
