I am still not quite convinced that ZFS is completely stable. I set
filesystemio_options to "none", increased the number of DBWR processes
and their slaves. Not everybody likes ZFS, as can be seen here:

I know that direct IO and asynchronous IO put quite heavy requirements
on both the file system and the OS, so I decided that removing that
would be the first thing to try.
