I don't and would be very interested in it.
Do you use Gnatsweb for accessing the affected databases?

If Gnatsweb locks the database just for submitting the edited problem (I
don't know whether it works this way), then this should be a safe
workaround.
BTW, Yngve, you said it happens in *one* of your databases. Is it
really so and if yes, is the database special in some aspect?

I've observed a similar problem when we were using GNATS 3.113 in my
previous work. However, I think it has never happen in the use of GNATS
3.113 in the company I work now.
I have the following hypotheses how this can happen:
- A web operation can finish for some reason (stopped browser operation
or something like that) and the CGI script is stopped before it
unlocks the database. I don't know whether this can really happen,
but it's the only explanation I had for the problems I experienced
(the problems always happened during problem editing by some quite
stupid users, they could do something weird).
- gnatsd crashes during Gnatsweb<->gnatsd communication. When I was
playing with gnatsd from GNATS 4, it stopped several times
unexpectedly. However, I don't know what Gnatsweb would do in such a
case, maybe it reacts differently and this hypothesis is invalid.
Unfortunately, I don't know what to do with the lock problem, unless you
can find out more information about the problem.
