It is a multi-threaded service, where potentially more than one thread can have an instance of the component (different instances!).

It is my understanding (or rather a guess, since I didn't find anything about it) that the "file list" concept is "local", per instance of the component and instances don't share "global" state (file list or otherwise).
Is this correct? Can a "file list" somehow leak from one instance to another (and get stuck there)?]]> Mon, 02 Mar 2015 17:15:14 +0000 http://www.quickpdf.org/forum/merge-wrong-files_topic3082_post12361.html#12361 <![CDATA[Merge wrong files? : Why not try clearing the file...]]> http://www.quickpdf.org/forum/merge-wrong-files_topic3082_post12360.html#12360 Author: Wheeley

Why not try clearing the file list after the merge? No use keeping it around.

QuickPDF COM DLL 7.22 used from .NET code (32-bit).

Windows service running multiple threads creating reports etc.

Often a packet of reports gets merged into a single document at the end.

Yesterday a client reported that they have received a combined report, which appeared to have merged some of their reports with reports belonging to a different company.

Our first line support was able to repeatedly reproduce the issue. Unfortunately by the time I got involved, the setup was changed and I couldn't see it happen anymore.
Nevertheless mixing data is quite a serious issue and I have to investigate further.

The individual reports appeared to have been generated fine, names are unique across the board (GUIDs), and the report packet lists are kept in two different databases. If there was some sort of database connection mix-up, then the client would have received a combined report in which all reports would have been from the wrong database.

At the moment the only plausible scenario I can come up with, is if the component somehow retained (or regained) some sort of state between runs.
Merge is done with ClearFileList/AddToFileList/MergeFileList.
An instance of the component is (supposedly) created and destroyed with every run.

Has anybody experienced a similar issue? Any ideas?
