Merged tickets missing from search

Hey all,

We’re running rt3.8.6, under FreeBSD, installed from ports. All
modifications done via (and there are not many).

The problem I’m seeing is this: we have a ticket which is not showing in
the list of unowned tickets. A second ticket has been merged into it
which was also unowned, and I suspect that’s related but I’m not sure why
or how, and I’m not able to duplicate it by merging two other tickets.

In fact, when I search the queue and say show all tickets, of any status,
that ticket still does not show in the list. It doesn’t show when I
browse the list.

Is there some DB-consistency check I can run? This ticket has gone
"phantom" on us, and it’s making our support folks wonder where else it
could happen.
