I had the same experience a month ago and apparently the problem was a
memory leak in the Linux kernel (2.2.9). If you are running kernel 2.2.9
upgrade to 2.2.12.

I am not sure whether the bbb.py scipt has an option to truncate at the
corrupted transaction, but you can simply truncate it to 301420091. Go in
the Zope/utilities folder and check the script bbb.py. You can read its
doc string by running it with no options. If I remember well something
like:

python bbb.py -er oids ../var/Data.fs  might work. It should show you the
corrupted position.
