xfer problems between 2.3.15 and 2.4.17

[gavin.gray at ed.ac.uk]

Any help with this would be much appreciated.

We keep coming across folders that once they have been migrated seem to 
have corrupt cyrus.index files. The only way to fix them is to remove the 
files and do a reconstruct. This is not a workable solution from our users 
point of view as is sets all the messages back to flaggged as new etc.

We have tried various tests, but we can't discover the cause of the 
corruption of the cyrus.index files.

regards,

Gavin Gray
