We were having problems with one of our jobs when trying to read from a sequential file stage with a QS plugin. I am linking the file stage directly to the plugin. I am getting inconsistent results with this setup. Sometimes the job runs fine (About 4 out of 5 times), other times it fails with an Access violation Error (DSP.ActiveRun at line 51 error) or simply hangs.
I tried putting a transformer between the file stage and the plugin and the problem seems have been solved. Atleast I havent been able to reproduce the problem in about 12 runs. I've had problems with other plugins (ORABulk and SQLBulk) when I was writing into them directly without using a transformer.
My question is if this is a known issue, (have any others run into similar problems) and that the QS plugin should as a matter of principle not directly connected to I/O stages, or am I doing something wrong ?

I can't really say specifically for the QS Stage (don't have it), but it is "good practice" to never link two passive stages directly together. I encourage people I mentor as a matter of course to always put a Transformer between passive stages like you mention, even if it "doesn't do anything" but pass the data through. Cuts way down on the odd, hard to explain errors.
