I haven't touched gastman in quite some time, but based on your bt I see a few spots where we can check for NULL to stop some segfaults.  I'm commiting a fix.  Let us know if it fixes it, I'm going to keep this bug open until then.
By: capouch (capouch) 2004-02-28 13:21:57.000-0600

The segfault is gone, but the underlying cause of it has now reared its head, at least as far as call parking is concerned.

Parking the call causes the gastman display to explode with false channel entries--10 of them in the simple park I just did.  8 of those then are stuck on the display after the call is gone.

These false channel entries (icons or list items) stick around forever.
By: capouch (capouch) 2004-02-28 13:45:28.000-0600

I should have played a while longer before that previous post.

Once the "many entries" phenom has reared its head (in my testing via a simple call park) gastman is still alive, but zombified.  Subsequent channel activity is not reflected in any of gastman's panes.
By: James Golovich (jamesgolovich) 2004-02-28 15:37:54.000-0600

I tried parking a call last night with gastman after I patched it and didn't have any problem.  This was on a mostly inactive system though.  I think gastman needs some pretty major work
By: capouch (capouch) 2004-03-05 02:20:24.000-0600

Could you post your parking confs?  I am suspicious that the flurry of extensions that suddenly appears upon parking may be related to the number of parking extensions that I have configured, and there may well be a bug there in other code that this is exposing. . .
By: Mark Spencer (markster) 2004-03-05 09:06:11.000-0600

How are you parking with gastman anyway?
By: capouch (capouch) 2004-03-05 11:53:56.000-0600

I'm not parking with gastman, but when I park calls, gastman freaks out, putting up channel icons all over the place and then becoming unusable.
By: Mark Spencer (markster) 2004-03-07 20:25:37.000-0600

Does this still happen?  Even with cvs-head?
By: capouch (capouch) 2004-03-08 02:02:17.000-0600

I just did a fresh cvs checkout (development) of asterisk and gastman.

Still happens.  As soon as I park a call, the display suddenly fills up with icons, some of them clones of the channels in use, others empty icons with no text.  None of the icons that remain after the call has been completed can be deleted.
By: Mark Spencer (markster) 2004-03-24 20:05:45.000-0600

Okay I just tried and don't have the problem.  I'm using zap to call in and zap to park.  are you using anything different?
By: Mark Spencer (markster) 2004-04-03 21:15:38.000-0600

Last we talked you were going to try another system.  What did you find out?
By: Mark Spencer (markster) 2004-04-04 15:58:09

I still cannot duplicate this problem on a CVS head system.  If you are able to duplicate it on a system running CVS head, find me on IRC and lets talk.
