[Freeswitch-users] Socket Error [Too many open files]

[Colin Morelli]

When you say "I set the configuration below" - did you set this by
executing the ulimit command or by editing /etc/security/limits.conf (or
the equivalent for your distro)? IIRC the ulimit commands only change the
limits for the current shell and its children. Depending on how FS is
launched, it may very well not be a child of the current shell (or it's
forking off as a different user), and as such those limits aren't applying.

You can run "cat /proc/FS_PID/limits" to see the actual limits imposed on
the FS process(es)

Best,
Colin
