Yes, I'm sure, anyways there is about 40G free space now on that drive and 
it's not so easy to suddenly fill it up

Nothing ususial, except I just noticed that at any time, not just when the 
problem arises,  the %slo-z value is about 97-99%. May be it has nothing 
to do with this problem, but on other similar servers it's not that high.

Last time two weeks ago the server was rebooted ungracefully and fsck'd in 
foreground (it has background_fsck="NO"). After that, I didn't have a 
possibility yet to reboot it in single-user. If I could do it remotely it 
would help but there is no KVM or anything there. Honestly I'm a bit 
afraid of doing "kill -1 1" or "reboot -qn".

The server is in production and there is no other server to substitute it 
during the downtime.
