Joegen, George,
I noticed some messages in my sipXproxy log from a hang on a customer system just today, which may or may not be pertinent. Besides the parsing errors, I also see messages such as this immediately before the hang: "2012-08-21T15:40:56.031862Z" :269589:NAT:WARNING:pbx1.sipdomain.com:SipUserAgent-2:B5EBAB 90:SipXProxy: "'83226727-F4CE51E8': Received unexpected event InviteRequest while in state 'WaitingForMediaOffer'" "2012-08-21T15:40:56.233883Z" :269590:SIP:WARNING:pbx1.sipdomain.com:SipRouter-15:B5DB9B90 :SipXProxy: "SipUserAgent::send INVITE request matches existing transaction" "2012-08-21T15:40:56.323512Z" :269591:SIP:ERR:pbx1.sipdomain.com:SipUserAgent-2:B5EBAB90:S ipXProxy: "SipUserAgent::handleMessage SIP message timeout expired with no matching transaction" "2012-08-21T15:40:56.414306Z" :269592:NAT:WARNING:pbx1.sipdomain.com:SipRouter-15:B5DB9B90 :SipXProxy: "'5FHSHt9cQ2XBS':Received unexpected event UpdateRequest while in state 'WaitingForInvite'" "2012-08-21T15:40:56.516706Z" :269593:NAT:WARNING:pbx1.sipdomain.com:SipUserAgent-2:B5EBAB 90:SipXProxy: "'5FHSHt9cQ2XBS': Received unexpected event UpdateRequest while in state 'WaitingForInvite'" "2012-08-21T15:40:56.523583Z" :269594:NAT:WARNING:pbx1.sipdomain.com:SipClientTcp-4212:B19 FAB90:SipXProxy: "'5FHSHt9cQ2XBS': Received unexpected event SuccessfulResponse while in state 'WaitingForInvite'" Since this has been happening to some of our customers more than once within a 24 hour period, in order to keep them from cancelling with us we've had to resort to a watchdog script which sends OPTIONS messages to the servers periodically and restarts sipXproxy if it fails to respond. Obviously this is just a band-aid workaround until we can resolve this issue, since this means they incur approximately 3-4 minutes of service interruption every time this happens.
