I cross-post to serdev as it is more relevant there.
Dear Hoa,
I don't see anything wrong there. Obviously, ser doesn't like the messages being
sent, but I don't see anything that can explain why it stops processing.
Do you have anything in the send or receive queue ? (netstat -nlp)
At the end of the logfile, do you continue to send messages, but ser does not even print
debug messages?
It seems that ser is handling resending etc after the last message was received, so I
cannot really attach the problem to a single message.
I think maybe somebody else need to follow up on this; I'm not really sure how to
proceed now. :-)

Hoa,
That server is not responding right now. But it would be helpful if you could provide
any log messages from ser and more info on processes running, what top shows etc.

Subject: [Serusers] Ser stop responding requests when scanned with SiVuS
Hi all
Yesterday, I downloaded and scanned my stable SER system (production), and it stoped
responding to Subscriber requests.
The Tool is at http://vopsecurity.org/sivus-1.09.exe, remember to have JRE installed
on Windows.
I deployed the configuration guideline at onsip, OpenSER 0.9.5
Anyone have tested the Security Scanner, pls. help
Brgds
Hoa
