[Freeswitch-users] Memory leak when using ESL

[Dmitry Sytchev]

I can confirm significant Freeswitch process memory growth over time
when ESL is used intensively, from 100MB in normal case to 700-900MB after
few hours of high esl load, though I have no valgrind check results, as I
can't do tests at production server.
With less than 300 channels in peak we have 900MB FS process size, never
shrinking back :(
