The interesting this is that this function is called only when dovecot-uidlist.lock has been created, i.e. when uidlist is locked, meaning nothing should have deleted the dovecot-uidlist while it was being written to, so this error just shouldn't happen.. So apparently the dotlocking just isn't working properly for your NFS servers. See if dotlock_use_excl=no helps?
