Primarily apache2 and also mysql are then consuming most of the CPU and memory. I checked the hardware with the Dell 32-bit diagnostic but could not find any errors. /var/log/message produces the following or similar output: May 24 09:06:44 server kernel: VM: killing process cron May 24 09:06:44 server kernel: __alloc_pages: 0-order allocation failed (gfp=0x1d2/0) May 24 09:06:44 server last message repeated 6 times May 24 09:06:44 server kernel: VM: killing process apache2 May 24 09:06:56 server logger: Hole TAFSYNOP-Wetterdaten... May 24 09:11:09 server kernel: __alloc_pages: 0-order allocation failed (gfp=0x1d2/0) [..] The server is then so slow tom react that the only way to get rid of the problem is to reset the server. What can we do to fix the problem? Thanks. Oliver
