Hi again I was contacted by a person who suggested to double-check vfs_cache_pressure setting. And it appeared that I had this setting set to 10000. That was a left-over from previously debugging OOM-killer case. When I removed this setting from sysctl.conf, I was able to greatly increase the time to crash/freeze. My server was able to withstand about a day of continuous write test. Nevertheless, it froze after that. Still it looks like something is wrong with RAID/filesystem co-operation.
But why should it be RAID/filesystem and not hardware related or another linux subsystem?
I would still like to debug the problem. Please help.
The only way to get more help and information is probably to attach a real serial console (i.e. ipmi-sol).
