[Freeswitch-users] unexplained RAM usage increase

Wed Jan 30 02:14:22 MSK 2013

Things like this are sad.  We depend on testing and reporting for our
releases.  If you wait months to bring up a problem.  It will spoil the
whole release.

If you you feel some leak has appeared suddenly, why can't you do git
bisect and find it?
