Fred Schnittke 10.Feb.09 03:29 PM a Web browser Domino Server 6.0.3 Windows 2003
We've been having a strange thing happen over the last 6 months. Out of the blue, our Domino (http) server stops responding for up to 10 minutes at a time. It happens roughly once a week, but I can find no persistent schedule or event that precipitates this hang.
We use Nagios to monitor ports 80 and 443, that's how we know when it goes down.
There are no messages in the console, or log files. If I do a "sh ta" I can see that the http task is listening on 80 and 443, but it is not reachable via web browser. I have complete network connectivity to the server otherwise.
I can find no indication whatsoever as to what the problem might be.
