Hi Juha,
I have investigated what you reported and indeed there was a bug with
wrong Cseq in Notify with expires=0 triggered by another event than the
receipt of a Subscribe present only in a db_mode!=DB_ONLY.
While testing I also found a problem with the expires parameter value in
the Subscription-Status header. There was a static buffer used twice
when building the extra headers and as a consequence this expires value
always had the last two digits '70'.
I have fixed these two problem in commit
cd1ff5364786f8b32058921be6f3216b48e34792. Please test and let me know
the results.
Regards,
Anca

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).
