I had a similar problem, where it looked like the openser slowed down, and 
then stopped accepting calls.
It got so bad I had to setup sipsak to send a message to the server every 
minute, and send a message to my phone when it didn't get a reply.
In the end it turned out it was being caused by the server not having a 
working DNS setting configuired in its network settings. Even though i had 
dns=no and rev_dns=no in the openser config, it seems something was trying to 
look-up the aliases that that server itself was listening on, or the realm of 
the clients...
It would run ok, but it was as though the multitude of failed dns lookups 
would finally halt the system, or something...
Anyway, after setting-up dns properly it was fine.
Another time I had something similar where the server seemed to slow way down, 
I had to lock-down the network card to 10mbit full-duplex. It was 
autoselecting 100mbit half-duplex.
Hope that helps someone... sometime...

Richard.
