[Freeswitch-users] Sofia reporting 480 - maximum number of sessions

Hi - I've a little calling-card application which uses FreeSWITCH as an engine via mod_event_socket. Every so often, it stops accepting incoming calls; the error shown on the console is that Sofia's got its maximum number of sessions active. This isn't down to: - sockets being left open; - there being too many sessions (status and sofia status both showed 12 sessions last time it happened, and my max_sessions is set to 1000); Any ideas? Cheers -- Dave
