[asterisk-users] SIP Problems continue...

[Ken Williams]

I spoke to soon.  Not an hour into the day this morning and we locked
up.  I'm back to sip debug enable & have turned sip history on, get me
the bug number and I'll contribute there.

Thanks,
Ken

Well, I removed and reinstalled Asterisk & Zaptel last night.  We
haven't had one lock up and we've had zero ghost channels kicking
around.  I copied my config files straight over, so I'm certain it's not
a dialplan issue (I was thinking the same thing you were, and I started
throwing hangup statements all over the place).  My best guess, I had
something conflicting with an older version/SVN that was causing grief.

We haven't had a day with zero crashes in 2 weeks, and it was
progressively getting worse where we were to the point of 4-5 crashes a
day.  Going an entire day with no crashes is extremely promissing.

I do have a lot of data I captured that I could contribute, but I'm not
sure we had the exact same problem.

There is an open bug report on this in the bug tracker already.

I need your help to find what's causing this issue and provided I can
get proper information from you, will spend time locating the bug.

First, enable SIP history and catch history for these calls that hang
with "sip show history"

Secondly, check the dialplan and tell me more. Where are you calling,
why doesn't the other end respond?
It's usually calls where we retransmit a number of times and then forget
to destroy the calls.

If I can get a better description so I can repeat this, I'm sure the bug
can be killed.

In the bug tracker, there's a patch that will help you. However, until I
find more exact information about the nature of these calls, I'm
unwilling to commit it. To commit a fix to a poorly defined issue is
usually causing more issues, something I can do in trunk but don't want
to do in release code.

Please send the required information directly to my e-mail address and
I'll take a look.
Thank you for your assistance with this bug.
