Hi,

I have two datamodules (mixed usage of TIBOXXX and TIB_xxx
components) that works just fine as a part of standart application.
First module contains only a singli TIBODatabase component,
second have a lot of IBO components that use a database from the
first datamodule. Second datamodule have a long initialization (it
reads data from a couple of tables in memory lists)

In addition, I have a NT service application that have four separate
threads handlin miscelanous tasks (all threads use TIB_xxx
components). Service works just fine.

Now I'm trying to put datamodules from the first application to the
separate thread as a part of my service application.

If I create datamodules as a part of service application creation
(construct before application.run or hook to
TService.OnServiceCreate) all work fine in most cases, I can access
code from datamodules from separate thread, but sometimes (because
of the long initialization) Windows service manager cannot run my
service (timeout)

I try to move datamodules creation to the same thread that uses it,
but witout luck:
Everytime, a second module initialization runs to random point and
one of the following occur:
- initialization hangs on random place
or
- in most cases, application raises an exception (on random stage!):
ISC Error Code 335544726 (error reading from the connection).

In most cases, Firebird is not answering to client requsts anymore
after that exception.

I'm using IBO 4.2.Ie, Firebird 1.03, connecting vi TCP/IP.
