I'm having a similar problem with an IntraWeb app..

Using D7, IW 7, IBO 4 and Firebird 1.5.3
The app is running on an XP machine.

The app will just lockup after some time in operation. It's
arbitrary, I can't seem to put my finger on what's making it lockup.
The IW debug screen reports active sessions but nothing connects to
the database after the lockup. I have to shut down the app and
restart it.

I can however lock it up every time from one of my computers that's
on the same physical network as the server. I don't know why this
one computer locks it up but other pc's in the hub will not lock it
up. Also certain users outside of the local network that access it
using the normal browser links can lock it up too.

There's no message when the lockup occurs, it just freezes!

Before I switched to IBO I was using the components that come with
Interbase. Every time I used the Commit statement it would do the
same lockup. When I switched to IBO the frequency of the lockups
decreased but I still get them occasionally.

Any ideas?

Thanks,
Wayne
