Hi,

Have a look at server logs and look for clue when server crashes. It may be a problem of configuration, not missing resources.
For example check the memory setting in php.ini - the default is 8MB and at some point I had a problem with that and had to increase it to 16MB (for you may be more, it may depend on the content you have. I don't remember the simptoms, but there was a entry in the log.)
Check the size of the database and tables. In some XOOPS versions the sessions table was growing very big ...
You may also temporary put a script to monitor the usage of resources ...

thanks for your answer!

the session table has been broken most of the times the server fails, any idea on how to fix this?? I can't upgrade to newer version as I have a lot of hacks :\

Hi,

I'm not aware of any fix, but you can install xoopscare module and, if you hace cron installed, set it to clear the table at some interval, or do this by hand...

thanks again Stefan, and how can I cron a MySQL sentence? What would the "command" be?? I guess it will be a linux command or something?

can you provide me an example please? :)

thanks again
