    I'm getting some log errors with clucene that I am having no luck tracking down on the

This looks relevant:

    I am considering switch to xapian (solr and java... pls noe) as the
    port is quite tempting from an ease of integration perspective, but the
    easiest solution would be to resolve these odd indexing errors.  Anyone
    have a clue?

dovecot-fts-xapian is easy to configure, but has a big downside compared
to solr in that the indexer runs as root.
Dovecot indexer does not run as root.

It does in the not entirely uncommon case where you have setup
dovecot-fts-xapian, have multiple system users rather than a single
uid owning all mailboxes, and need to index all mailboxes.
PID USERNAME PRI NICE  SIZE   RES STATE     WAIT      TIME    CPU COMMAND
44468 root       2    0   11M   18M sleep/6   netio     1:41 68.36% doveadm index -A *
With solr the indexing is done out-of-process and typically under a
safe uid.
