Is there ever anything after the "Invalid data:" text? It seems anyway that concurrent reading/writing isn't working as expected in dovecot-uidlist. Most likely something to do with NFS.

Can you reproduce this easily by just running "imaptest" with some test account (it'll delete mails)? See https://imapwiki.org/ImapTest - it's also available in dovecot-imaptest package in repo.dovecot.org.
