Hello,

// Using the latest driver sources, the problem has not gone away..

We are using a home made connection pool, and are experiencing what seems to
be the same problem.

But we are NOT using the build in pool (FBWrappingDataSource).

Of course I am not completely sure if our code is correct, but we have tried
to find the error for some time and we just can´t.

Previous we "recycled" the connections every 15 minutes and got the error
aprox. once a week.

Now we only recycle every 6 hours, and until now have not had the error in 1
month.

When we use other database's (ex. Postgres), we have never seen a similar
problem.

I know this description is not enough for anyone to really help, but the
scenario is a little too complicated for me to enclose code-snippets.

Anyway I just wanted you to know "You are not alone" ;-)

Regards,
Claus

Ps: Except for this "small" problem, we are VERY satisfied with the driver.
You guys are doing a great job :-)
