We had the exact same issue with MySQL and were assured it was a fault with the ODBC driver on CentOS.

I’m concerned to hear this is actually a FS issue and not a DB driver issue. Concerned. Not surprised. 

Are you using xml_curl registrations by chance?

Dear All,

I have a freeswitch (1.6.20) server in production with db configured to postgresql through pgpool2. This system hangs time to time and has become a major issue. It happen only to the internal profile where our UACs connects through webrtc. After the incident profile stop responding to cli commands, only solution is restarting the entire application.  I managed to get the back trace which indicate system waiting forever for profile database mutex. Further, It seems thread #19 is waiting for result from pgsql server cause this issue. Please find the back trace link below,

Has anyone experienced this issue before, what is the solution for this. 

Best Regards,
Sukitha.
