Hello,

Our BM3.8 SP4_IR2/NW6.5SP4 server stops responding on a regular basis.
This server is configured according to Craig's manual and tips.

This happens on all interfaces (private and public). No warnings, no log-
entries. The only logging I have is from our DMZ mailgateway which
connects at a generic proxy at port 25 (see at the end of my post).

The only things I noticed are the counters at the Generic Proxy Statistics
window:

Number of TCP Requests : 304552
Number of Active TCP Connections : 302669 (!)
Amount of TCP Data (Bytes) Tunnelled : 295760110
Number of TCP ACL Denials : 43
Number of UDP Request : 0
Number of Active UDP Connections : 0
Amount of UDP Data (Bytes) Tunnelled : 0
Number of UDP ACL Denials : 0

At the Novell BorderManager FastCache Current Activity window, I noticed:

Connections in use: 1511
Connections awaiting tear down: 37
Client Connections: 32 Idle: 0
Server Connections: 1517 Idle: 14

Any ideas?
Kind regards,

Here's a little piece of the mailgateway's logging:
