[ZODB-Dev] problem with _p_mtime

[Alan Runyan]

We run consistency checks on the ZODB - the same as we do on SVN -- nightly.

  http://svn.zope.org/ZODB/trunk/src/ZODB/scripts
  - fstest.py
  - checkbtrees.py
  - fsrefs.py

We have never had corruption in years.
But I just wanted to ask what people are doing to find any problems
with consistency; so the problem can be solved ASAP.

Miles, have you run any of these scripts across your production ZODB?

cheers
alan
