Description:This started happening once there were more people introduced to the feature. We then offloaded the feature to another server and directed all calls to the new server via trunking, and that started crashing. At least I was able to get a core dump and backtrace without disturbing the main PBX server.

There have been tons of fixes added to parking since 1.4.23.  Could I get you to try with a fresh checkout from http://svn.digium.com/svn/asterisk/branches/1.4 and see if the problem still exists?  Also, having some examples, logs, config files, etc. would make it easier to track down and reproduce if the problem does still exist in the 1.4 branch.

I've just uploaded the full log file and my asterisk configuration. Everything is pretty vanilla, since I setup a server just for parking.

Ok.  Thanks.  Let me know when you've tried the 1.4 SVN branch.

I'm having a hard time compiling the 1.4 branch. Getting this error.

Looks like a DAHDI issue.  What version of dahdi are you using?  It compiles fine for me with a recent checkout of dahdi and asterisk 1.4.

I had the latest stable DAHDI drivers and tools (2.1.0.3 and 2.1.0.2 respectively). I now have checked out the latest SVN and installed it, still have the problem. Does this have anything to do w/ the fact that I'm running the following configuration: RHEL5.3 x64? I'm still able to compile the 1.4.23.1 release just fine.

Ok, I reproduced the compile problem using a Centos 5.2 x86_64 vm.  Try the dahdicompile.patch.txt and see if it allows you to get through the compile; then see if the reported problem is fixed.

Patch was successful. Will be monitoring for segfaults in the next few days and will update here. Thanks.

jrgutier: It has been a week since your last message. Is everything well?
By: Jose Roberto Gutierrez (jrgutier) 2009-02-18 14:00:58.000-0600

So far, yes. It has had an uptime of 6 days without any crashing, after the you guys gave me that patch to get it to compile. I'm going to recompile to an optimized non-debug build this next week.

I'm having trouble compiling asteris 1.6.0.6 due to the user.h errors.  I tried to use this patch but it failed to patch.
By: Jeremy S (jeremy1) 2009-02-24 17:11:39.000-0600

I'm having the same problem as hulber. Also see:

http://bugs.digium.com/view.php?id=13892&nbn=36#100667

I manually applied the changes and still receive the following error upon compilation:

...
  [LD] app_dahdibarge.o -> app_dahdibarge.so
  [CC] app_dahdiras.c -> app_dahdiras.o
app_dahdiras.c:47:35: error: asterisk/dahdi_compat.h: No such file or directory
In file included from app_dahdiras.c:53:
/usr/include/dahdi/user.h:736: error: expected specifier-qualifier-list before ‘__s32’
/usr/include/dahdi/user.h:939: error: expected specifier-qualifier-list before ‘__s32’
make[1]: *** [app_dahdiras.o] Error 1
make: *** [apps] Error 2

So I guess the question now is: Where is dahdi_compat.h?


By: Terry Wilson (twilson) 2009-02-25 16:21:58.000-0600

The compiling issue for both 1.4 and 1.6.0 has been fixed in SVN and will be available in the next release.  This is a bug relating to parking, so I'm going to go ahead and close it since the reporter has stopped getting the crashes.
