[solved] Wait IO suddenly extremely high (exploit ?), crashing the server
(sorry, I tried to modify the title of the thread, but couldn't)

well, technically not solved. its pixie dust.
what type of filesystem, IO scheduler, do you run |
My file system is ext4 if that's what you ask.
As for the IO scheduler, I don't know ... how do I check it ? I just know my hard drive is in a RAID5 cluster, and 1&1 advised me to go for a dedicated server to have faster IO exchanges (because they failed to understand the 'huge waitIO problem' was not normal in my case) |
