[OPEN-ILS-DEV] Assistance request with a SIP connection problem

You should have the customer check the /var/log/syslog on their SIP2 server
for error messages.

The most relevant lines would likely contain the following text:

read_SIP_packet (try [a number]) ERROR:

If they don't find that in the logs, then more digging will be required.
