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).
