You're trying to sync a Maildir while users are reading messages.

This causes files to disappear just behind csync2's foot.

csyncing rapidly-changing hierarchies with csync2 is not suggested. Use "coda" or another distributed/fail-safe fs to gain HA on them.

csycn2 is meant to keeps "static" files in sync. I use it to sync some config files and static web files which have to be shared across some loosely-connected systems. This kind of files aren't rapidly-changing and it works fine that way.

Cheers,
