[Freeswitch-users] Error message " [ERR] switch_cpp.cpp:48 Cannot queue any more events“

[Steven Ayre]

Sessions are not queued events. They're separate limits.

You can have 1 session at a time and still hit the event queue limit if
you're not pulling events out.

As for 1000 sessions when there's a 100 trunk limit - sounds like you're
originating many more sessions than the trunk can handle. It won't block a
session until there's a line available, that session will just fail (and
from the sound of it instantly be replaced by you). I'd suggest 99% of your
calls are probably failing. What do your logs/CDRs tell you? You need to
wait until a channel is available before you start a call.
