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

[Sergey Okhapkin]

Looks like I found a work around. I set <param name="global_heartbeat" 
value="off"/> in nibblebill.conf.xml and execute "nibblebill heartbeat 60" in 
dialplan. No more unbounded memory growth. As soon as I set global_heartbeat, 
memory starts grow again. Go figure...
