[Freeswitch-users] freeswitch memory leakage.

[Michael Jerris]

That being said.. there is a known issue in mod_vlc in 1.4 that leaks but I don't think enough to necessarily describe what you are seeing.  We are doing a complete rewrite of that module for 1.6 so that fix may not make it down to 1.4, still to be seen.

Usually FreeSWITCH builds up a memory pool and won't release that back to the system until after shutdown, but I don't normally see that go above about 1.2GB of RAM in any of the systems I work on (though they do not use mod_vlc).
