[OpenSIPS-Users] FW: Opensips 1.6.4 doesn't send an OK response under high load

Mon Sep 10 19:51:49 CEST 2012

Hi Binan,

I understand what do you say with "play around TCP connection lifetime"
however I don't get the part you say "check the database". I don't have any
database, opensips is working without any DB.
Which database are you talking about?

Thanks
Diego
