And this didn't crash in any version prior to 1.4.27-rc2? (i.e. 1.4.27-rc1?)

I have upgraded from 1.4.21 and i didn't have a single crash with this version.
I see that in r222691 there is an update in chan_misdn code relative to astdtmf configuration option that i use. Do you think there is a relationship with this crash?

Maybe your crashes are related to mine. Do asterisk randomly crashes or did it goes down only if a misdn connection is ending ?

With DON'T OPTIMIZE the crashes are less frequent in the whole day but as you can see there are always when the office open at 7:00AM and the staff start to phone:

Hmm,

that's the same i monitor.. mostly our pbx went down after i power it on (It didn't run the whool day) and it need to handle the first calls. I'am still not able to change the system to debug mode and my test system didn't generate the problem in the moment. (We run a 1.4.26er system)
As i noted in my bug report i think it's the hangup process. In the moment i think it's an access to channel elements already freed priviously in the hang process but maybe i misinterpret the situation. (Sorry for not offerening hard facts.)

hi,
here is a patch that might solve this issue (issue which already existed in Asterisk 1.4.26, and which is not 100% reproductible because it is an uninitialized memory on the stack bug)
By: Francesco Romano (francesco_r) 2009-10-27 03:03:17

I have patched asterisk 1.4 SVN and seems stable, 3 days without crash. I think you can merge this patch and close this issue. Thank you.
