When looking at the web site for user stats, users often see a message about the server being overloaded. The BWM and server all seem ok wrt memory, cpu etc. Rebooting the server fixes it.
Am I doing anything wrong?

It seems some users have long lasting connections or something like that. How many users do you have altogether? The built-in web-server is supposed to serve at most 10 clients at a time, but I can increase this number.

I have about 30 users in total, all with web access enabled. I doubt that any more than 1 would check the use at a time. Also when it goes into that mode it stays there till reboot.

Could you please provide some more information? When it happens again, please open a command prompt and launch netstat -n. This will print all the connections established to the server. Then simply save it to a file using this command: netstat -n > myfile.txt and post the the file here.

I'm having the same issue. Here is a copy of when I did netstat -n.

10 connections.
Any Ideas?

Restarting the the service repaired the problem. Easy method was to disable the Web Usage Report and re-enable. But a prevention would be good smile
