My redhat server is crashing every three weeks or so at 4:15am ish on Sunday mornings. (well it was sundays the last two have been Thursday mornings at 4:15ish) Looking at the logs (mysql, httpd, messages) there are no clues as to why. They just seem to stop.
I ran a little script to take memory readings every 15 minutes and it too stops (with normal readings) at this time.
The server is remote at a provider so I can only access it via the web. I use Plesk.
It appears to be a set job or something that is causing the issue. I can see nothing in crontab.
So my question is...has anyone else had this and can offer advice? Failing that.
Does any one know of a way to get more detailed logging than that offered by the messages file? I was thinking of a black box style recording program or maybe something as simple as an option somewhere to increase the level of reporting in the messages log.
