[rt-users] Full text indexing error with MySQL

[Omen Wild]

I activated the full text indexing under Ubuntu 16.04 (request-tracker4
4.2.12-5) and (mysql-server 5.7.13-0ubuntu0.16.04.2). Both the initial
indexing and subsequent calls to rt-fulltext-indexer have the same error:

I saw a similar email back in January and one of the comments asked about
disk space. The disk has plenty of space (only 10% full) and `systemctl
status mysql` shows the mysql process is still running. Entering RT
and doing searches works too, so the error is misleading or wrong.

Any ideas?

Thanks,
