By that I mean that the server is up and running, apache appears to be up and running (no errors like in this thread http://moodle.org/mod/forum/discuss.php?d=51838) and mySQl appears to be running.
There are no obvious messages coming through.
If you put the address of the moodle into a browser it chugs for a while and then comes back with page cannot be found.
If you try to stop and restart MySQl it won't start.
If you reboot the server all is well, but this isn't terribly good having to reboot the server every morning.
We are using Windows 2003 server, Apache 2, php 5.2, Moodle 1.5.2, MySQl 4.1.9
Has anyone else run into this sort of thing and if so how did you cure it please?
I'm not convinced it is the appache, but I'm open to persuasion.
I've tried restarting the MySql service in this situation and it won't stop and it won't restart. We then end up rebooting and all is well.
I think my biggest issue is not knowing enough about anything to actually be looking in the right place!
Thanks for the suggestion, I'll keep pottering at it and I'm sure the light will shine eventually!
If the problem manifests itself overnight, one place to start looking is in the Scheduled Tasks. Are there any jobs scheduled in there and could possibly be overrunning? Take a look at the Properties -> Settings tab and, as an example, set them to stop after say 4hrs. I suppose that another thing to do is look back through any changes that have been made on the server - but that would depend on how well you document changes on the moodle server.
I think my problem lies in that I know what I have done to Moodle and MySql but I have no way of knowing what the server team is doing to the server in terms of patching Windows and so forth.
I have a suspicion it may well be either a network backup or windows patching causing my problems now, but I don't know how to track down what exactly is going on.
I think I was hoping someone else would have had the same issue and could narrow my field of search.
Thanks for your help.
I shall investigate the backups, it seems a strong contender.
Can somebody enlighten me on how this is related to "Servers and Performance", please?
I'm open to it being in the wrong forum although it is definitely a performance issue - it isn't performing at all when it stops and it is probably stopping because of some sort of server issue.
The server itself is a Windows 2003 server with Quad xeon processors and 4gb Ram so I'm fairly sure it is up to handling the traffic we are sending at it but something is impacting on the performance.
