A guess would be that this is likely due to the endianess of the multiple architectures that the index is being accessed with. We have the same issue here across i686/x86_64/sparc. I'm about to post to an older email thread about this as well.
This is a good guess. We use a mixture of i386 and x86_64. This is not an "endedness" conflict, but could be the problem for other reasons.
So you use NFS?
Clients mount off of the server, but dovecot (IMAP) connections are made directly. Home directories are not mounted, so I do not think NFS can be affecting dovecot. I think the problem is due to 2 users using the same account making simultaneous access. It could be that the users need to be on machines with differing architectures (i386 and x86_64 in our case).
Anything more I can tell you?
