We have a problem with our fresh installed BM3.8 servers using mailproxy.
We only use mailproxy to get access to our pop3 boxes outside. Today
this pop3 server was down for a few minutes. All our BM servers (in
different locations and in different trees) got an abend while this
server was down. The server console said "unable to connect to pop3
server" right before and after the abend, so I think the abend might be
related to the mailproxy.
Here are our abend.logs:

All servers are patched according to Craig's site (incl. proxy.nlm from
SP4_IR2). We also use his proxy.cfg file.

Any ideas how we can troubleshoot this problem?
