[Freeswitch-users] Memory leak in mod_nibblebill or in ODBC core?

Mon Apr 19 09:57:40 PDT 2010

yes its a function of the sofia-sip project, but did you wait before you
stopped it?
We have people sending non stop 200+calls a second complaining about no
leaks.
So if you have some real problem it's going to be your network conditions
and interop with your
providers causing an edge case with the SIP stack itself who has it's own
list and irc channel.
