| Description: | Lately with our internal copy of dahdi trunk we started getting occasional panics on disconnects. This started only after merging post-2.2 changes. My suspect so far is r6794 (the drivers reference counting) but I haven't had the time to trace this issue yet. Scenario: 1. disconnecting a device 2. Sending Asterisk a "remove" event 3. Asterisk closes the file descriptor 4. Panic | ||

Thanks! By: Tzafrir Cohen (tzafrir) 2009-09-21 11:26:51 This seems to have been resolved in r7066 , which fixes a regression added in r6794 : Don't dereference the span after a channel was closed. | ||
