[reSIProcate] Issues with ClientSubscription issuing local 408 timeouts

[Aron Rosenberg]

So our implementation with ClientSubscription works most of the time,
however every now and then when we create a new ClientSubscription about
half of the requests will generate a local 408 even though the
subscription was already created and ACK'ed and NOTIFY'ied.

 

Attached is the resip log without DNS or STATS catagories (we don't log
those in our application) for a single SUBSCRIBE request from 
aron at sip.sightspeed.com to roger at sip.sightspeed.com .

Also attached is a pcap file showing the full transaction with our
OpenSER presence server.

 

The pcap and log file shows all the behavior:

 

SUBSCRIBE -> 202 OK -> NOTIFY -> 200 OK behavior. However, you will keep
seeing the client issuing retransmissions on the initial SUBSCRIBE
request even though the 202OK and NOTIFY came in.

 

Any help would be appreciated. It seems like a second AppDialog set is
getting created if you look at the resip log, but I can't figure out why
it wasn't matching the first one, or why this is a transient issue that
doesn't happen all the time (or if it is an OpenSER issue)

 

Resiprocate version is 1.0 with most of the patches that made it into
1.1. Will try a fully up2date head version too see if this exists in the
latest version
