[Freeswitch-users] Memory leak when using ESL

[Anthony Minessale]

You are showing valgrind traces of ESL client code but now you are saying
your FS process has memory growth not the ESL app?
You should be doing this on jira and you should have more details about the
env.
This mailing list is not for bug reports.

I did push a patch for what I think might be the problem you showed on esl
lib.

FS can use up to a gig of memory without giving it back.  To make sure you
have a real memory leak you need to have it never peak but continue to grow.
