[Freeswitch-users] FS freeze with 100% CPU rate frequently

[Luis Daniel Lucio Quiroz]

+1 Chris, I have many VPS running FS without issues.

Anyway, Eric has not given any useful information to help him. Not only
release, but architecture as well. Are you using a specific xml handler?
how the xml handler feeds? what is your ulimit parameters?

In my experience, when DB struggles and connection brakes, ODBC does not
recover nicely always. 100% cpu utilization is, in sometimes linked to
zombie processes. Freeswitch may be waiting for a zombie process.

I think this is more a sysadmin issue than voip.
