I think I may have found the issue affecting our HP DL360 G7s (but I don't begin to understand why this problem does not happen on our HP DL360 G5 with a slower disk subsystem).
Recap: Running tcpdump on SIP UDP along with Asterisk 1.8.* causes Autodestruct ... owner in place ... BYE messages when running on our new G7 servers (generally once the box has more than 100 B2BUA calls up and running). Items that had no effect: updated firmware, later versions of Asterisk 1.8.* (we are running 1.8.7.0, later versions crash after half a million calls), enable/disable PAE kernel, tune/adjust AGI script to make sure end-of-call processing is always fast (hi-res timers confirm). I was even able to reproduce the problem using SIPp to generate a high call rate with no RTP (SIP signalling only). Reading all the various threads on Autodestruct ... BYE messages, I found the thread about using radius and having a non-responsive radius server causing the CDR process to delay and generate this message. I'm NOT using radius, and the only Asterisk CDR processing I have enabled is the out-of-the-box CSV file. On a hunch, I disabled CDR processing completely in cdr.conf ([general] enable=no) and now the Autodestruct messages are gone. I've even pushed the load to twice the normal peak and still no Autodestruct complaints. It would appear for whatever reason, there was some delay/blocking writing CDRs to the csv file? I do still see channels that appear stuck in "Rx: BYE" state and that must be related to other possibly resolved bugs in after 1.8.7.0? (And I do see those as well on the DL360 G5 boxes that just seem to run with no issue). Next step will hopefully to get the latest 1.8.current up and running (as long as it doesn't crash like 1.8.12.2 has with the same traffic). -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
