I currently have a Vicidial Setup of 2 servers sharing a common database.

While dialing and looking through the asterisk screen, I get a lot of the following in between calls:-

Mar 12 11:52:51 WARNING[2529]: channel.c:780 channel_find_locked: Avoided deadlock for '0x82a59b8', 9 retries!

Does anyone have any idea what this is about?

Asterisk Version: 1.2.24

That error means a problem with sending/receiving data from a device, whether it be a VOIP channel or a recording.

Are you doing recording?

Can you tell what channel these WARNINGs are from?

Yes, we are doing recordings and the recordings have a problem where they are sped up and are completely unusable.

Is there a way I can tell what channel they're from?

I can post more of the log here if that would help.

What is the loadavg when this happens?

Have you tried recording to a RAM drive?

by **aster1** » Thu Mar 13, 2008 5:36 am

I have those problems on one server . Recording to both ram drive or hard drive causes this . Ztdummy as timer and load is around ~0.5-0.6 .Happens with sip as well as IAX . That's why i wanted to try asterisk 1.4 and see if this goes away .

It possibly could be a bandwidth issue then, not having enough for the number of channels you are trying ot push through, or too high latency.

Right now, the recordings are being stored on the hard drive of another dedicated computer on the network which is mounted via NFS.

The thing about that is we had the problem even when the Dialer Machine was recording on it's own hard drive.

Should I post the extensions.conf for both the dialers?

We did have a bandwidth issue but that was resolved. Each dialer machine is hooked up to it's own internet connection so that should be a non issue as far as I can see. I'll double check to make sure.
