[Freeswitch-users] Channels never hangup?

Hello, Had a real emergency today, and I'm not sure it's done. All of a sudden, everything is busy. I look at my channel count, and 200 channels (max allowed). We usually don't see more than 40. Some of these calls were two hours old. I know nobody checks voice mail for two hours. I tried a test call, and it never left the channel list. Restarted freeswitch, same thing happened a second time. 200 sessions, 200 stuck channels. Restarted the machine. Same thing again. I haven't touched anything in two days - what did I do? HELP -Tim
