[OpenSIPS-Users] Possible memory leak related to AVPs

[Răzvan Crainea]

Hi, Mickael!

I don't know what exactly might cause the leak. What you can do is to 
try to get a core dump (using tools like gcore) during low (or 
unexisting) traffic and try to see what do the AVPs that are leaking 
contain. Are you using QM debug?

Best regards,
