I experience similar problems with rel_0_9_0 SER on RedHat 9. It could
work for a week without problems, then it could crash 2 times within a
day on reception of REGISTER requests from the same agents that worked
fine before. The server load is very low, (one to ten registered
clients; one to six concurrent calls).
I thought my problems could be caused by oracle module I use or by
some modifications to SER sources, but looks like they are very
similar to yours. Do you use any non-standard modules or SER patches
as I do?
A bit more details to compare: NAT-Pass evaluation (proprietary NAT
traversal solution) is installed on the same PC with SER. Some
requests go directly to SER, but some go via NAT-Pass.
I successfully stress-tested my SER with hundreds of thousands
REGISTER requests via sipsak. So, I suspect the problem could be in a
particular request field formatting or in particular sequence of
I have no time right now to investigate the problem in deep. But
certainly I'll try to catch it in near future.
