Thread was being aborted in win2003 server. Back ground thread reading MS access database, no redirects or transfers.


Thread was being aborted exception is thrown by my asp.net

I hope someone could help me with this error that I get in windows
2003 server. This error has not occured with the same application in
windows 2000 professional computers that are also lot older and less

I have an application that starts a background thread that mainly
reads data from ms access database (approximately 0,5 GB access db)
with oledb connection and then calculates something and writes to
another database.

I have tracked down that this exception by IIS is thrown in the
following code when the dataadapter should be filled with data from ms
access database.

OleDbDataAdapter dataadapter = new OleDbDataAdapter(command);
DataSet ds = new DataSet();

And this code should be totally OK as such since the same method is
run about thousand times before this exception is thrown and the
thread is terminated and when the same thing is run with console
application everything runs perfectly well.

Has anyone run to same kind of problem ?
There are many questions in these newsgroups about direct and transfer
commands sending thread was being aborted, but this is not a case for
which that situation would apply. This is a new thread created by the
asp.net code and should run until the operation is finished, but does
not do that right now.

I read that IIS could unload application domain by throwing this
exception if it thinks that a crash,timeout,deadlock or memory has
been exceeded. But this should not do that since console application
on the same win2003 server runs just fine and on slower and older
win2000 machines the application also performs okey.

Also tried to change connection timeout parameter of IIS server, but
it did not help (from 120 to 1200)

Thank you in advance for reading and for possible answers that might
help me to figure a way out of this problematic situation.
