I got the following error message in Unix log: http://dl.dropbox.com/u/72686/outOfMemory.png
I'm just running a drupal website. What does that mean ? Is related to the RAM of my unix system ?
Or is some other functionality ?
When finished memory, system kill apache process.
1 Reduced MaxSpareServers,MaxClients
2 Add memory and then use optimal config:
It's most likely a RAM problem, you might run out of memory and your system invoke the OOM-killer and start killing processes to free up memory, I guess this is a system with little RAM and apache is eating that RAM.
More information about your server, confiruation of apache and your site habits would be useful in this case as it could shed some light as to whether you need more RAM or just better configure your apache.
Hope that helped
