[Freeswitch-users] registration fails after several hours - FS problem?

[Anthony Minessale]

what would help is if you can get a similar log with the siptrace on
the profile and sofia global loglevel 9
The key is the catch the very first time it goes wrong, possibly a
full pcap of any network activity as well to look for more clues.

This appears to be some sort of strange environmental condition or
particular edge case that breaks the sip lib internally.

I don't want to put then in public areas since they contain security info. Please review my steps below. I don't know FS or Linux internals but it seems a lot like a timing issue where two processes are not communicating with each other since retry messages occur but there is no SIP tracing going on. THANKS SO MUCH!

>> 7. Copied and updated Linux to git 10-29 to be the same as Mac box. Again, no problems for 12 hours!

>> OSX
>> 8. Went back to the mac to provide you with pcap and dump. In about 15 minutes FS lost 2 ITSPs. Here are messages issues during pcap/dump, NOTE clock message which is first I have seen of it:

>> Note: I had the Mini set to no sleep even though it worked with Linux sleep. I found a couple others on the web who had the same problem and one had written a script to restart FS every 4 hours. Fried (tired) right now and cant find the URL but it was from Jan 2010.
>>
>> One last thing to mention is that on osX using auto-nat:1.2.3.4 and some expiry parms, etc that may have triggered activity, FS worked much longer than on static. This is why I think it's timer or sync related and only on osX.
