Hi,<BR>
<BR>
There are lots of CSeq race conditions when subs_db_mode is DB only. I am working on adding separate notifier processes to presence which, amongst other things, will fix this.<BR>
<BR>
I had intended to get this into master last week, but other stuff came up and the development has been a bit more complicated than I'd hoped. I expect to commit these changes (which should fix your problem) sometime over the next week.<BR>
<BR>

while doing some presence tests with master i noticed that when presence
server sends notify that terminates subscription due to change in xcap
authorization rules, cseq in the notify is same as in previous one.
rfc3261 says in 12.2.1 UAC Behavior:
Requests within a dialog MUST contain strictly monotonically
increasing and contiguous CSeq sequence numbers (increasing-by-one)
in each direction (excepting ACK and CANCEL of course, whose numbers
equal the requests being acknowledged or cancelled).
so this looks like a bug to twinkle (and me). below is sip debug from
twinkle (subscriber).
