What do you exactly mean by stress test? Just copying files from
somewhere - maybe from /dev/zero to /dev/sda1 (which is my
ext3) with various dd's ?

Hmm... Not all will fail, since the ext3 is mounted writable for 5
seconds. So should I write just random files to /dev/sda1 (my ext3) in
these 5 second periods of time and see if the foreground script prints
any errors? Is this the purpose of the test?

I made the change. It doesn't change the problem, though.
Have a nice day,
