I've been using H2 on a desktop machine for several months now, and I must
confirm it works nicely. The only problem I've encountered so far is that
after some time the periodic cleanup starts to fail with error...
ioctl: Numerical argument out of domain
... with kernel output like this...

bulkfree pass statistics (0.00% storage processed):
bulkfree was aborted
I suspect this to be result of dirty unmounts (the machine has experienced
some hard lockups), or maybe it's somehow related to snapshots (I've
written a short shell script that maintains snapshots as a part of daily
cron).
Matt, do you have any idea how to fix this so that bulkfree can finish
successfully?
Thank you.
