Is anyone else seeing lockups on WZR-HP-G300NH flash?

I have an sqlite3 database that I am accessing, but it causes the file system to eventually get "stuck". This is typically for example a "find /overlay"
stopping before getting to the file in question, and requiring a ctrl-C.
On reboot, there are often jffs2 errors and possibly an unusable
system.

Suspecting that sqlite3 was causing some interaction with overlay/flash,
I put the db in /tmp (which is much faster to access anyway) and then
back it up every few minutes to flash if it changes.  However, the
problem persists.  The database is the order of 200-500k. The problem
occurs after perhaps 50 copies. This  is bleeding edge trunk.
I turned on many of the kernel debug options to spot deadlocks, etc,
but still nothing.

So, I don't have much to go on.  Suggestions on how to resolve
this welcome.
