Comments: | By: zoa (zoa) 2003-12-28 13:34:28.000-0600 i prefer it to crash than to load normally :) By: mochouinard (mochouinard) 2003-12-28 14:02:41.000-0600 Hope your joking hehe ;) Segment fault is never good, mean some error or something is not well handled. Witch could cause problem in different situation. I would like better a normal exit of asterisk and saying the channel you configure isn't a valid one or something By: Brian West (bkw918) 2003-12-28 14:31:19.000-0600 It doesn't crash if you configure you zaptel and zapata correctly. By: mochouinard (mochouinard) 2003-12-28 16:36:30.000-0600 It shouldn't still crash, it can stop, exit loading or what ever, but not crash. Like I said earlyer, crash mean memory or error checking or something wasn't done correctly. By: Tilghman Lesher (tilghman) 2003-12-28 17:20:46.000-0600 What exactly is wrong with your zapata.conf? I've always had Asterisk die, but not crash on this error. By: mochouinard (mochouinard) 2003-12-28 17:39:41.000-0600 put a channel =>99 and 99 isn't a valid channel, it will crash on load.. By: jrollyson (jrollyson) 2004-01-09 01:14:54.000-0600 While a crash isn't good, Asterisk uses the zaptel device for timing, and certian features break without it. Also, in a common VoIP internal/Zap external configuration, a zaptel failure means no outside lines, so refusing to load under these circumstances may be appropriate. In any case, the messages that preceed give someone a good idea of what the problem is. By: Brian West (bkw918) 2004-01-09 11:20:44.000-0600 Bug 736 has been applied please let me know if that helps. By: mochouinard (mochouinard) 2004-01-10 01:26:28.000-0600 I tested it again with CVS-01/10/04-02:10:44 and problem still occur By: Tilghman Lesher (tilghman) 2004-01-11 20:50:28.000-0600 Can you post a 'bt full' from the corefile you get? That would really help us squash this bug.
