Indy is definately thread-safe <g> but I have doubts about dbExpress.
I suggest you to replicate your minimal demo application with UIB and
see if you get any difference. Sorry to be of no help but I have
abandoned dbX before I got into the server applications business.

<SNIP>

C> Did I miss something here?

well, a bunch of try/finally blocks, a try/except block to intercept
and log exceptions (as you might know, an exception raised in a
secondary thread does not reach the main thread's default handler) and
explicit opening/closing of the connection and transaction. I
wouldn't qualify any of these as the possible cause for your problem,
it just gives a sloppy feeling.

That's what makes me suspect about dbX.
