Hi,
thanks for detailed report. This error has already shown, but I was not
able to find it.
Does this error occur if the subscription is destroyed by client
(SUBSCRIBE with zero timeout) or only when expires from timer? BTW, what
expiration time (Expires header field value) had the last processed
SUBSCRIBE request?
Please, could you try it with current CVS version? It needs a bit
modified config file, but it would be very interesting for me to know if it
is already corrected there or not.
thanks,
Vaclav

Hi,
I'm getting a segfault error while running the latest presence server snapshot
(ser-0.10.99-dev35-pa-4.2). The scenario is:
UA SER
SUBSCRIBE ---------->
200 <----------
NOTIFY <----------
200 ---------->
Everything is fine until the subscription expires, at which point the PA module segfaults
and generates a core file. Any suggestions on this? (logfile and backtrace from gdb are
attached).
