Hello!
 
Somehow we've got too many capture.exe processes that hang in the memory. They do nothing. We use PDFRedirect (2.1.911) to print approx. 1000-3000 files per day on ~380 batch printers. Here is a shot from pslist:

Why don't they close for hours?

Hi,

   I will take a look. Capture.exe is started by the printer when it receives a new print job. Capture.exe waits to receive the printer data, and then converts it into a PDF. If yu send a lot of print jobs very quickly, then the Windows Print spooler may become overloaded, and may not send the printer dat right away, which is why you may have these Capture.exe's just there, waiting for the data to come through.

   There is a timer inside Capture.exe which will cause it to quit after a while if it does not receive any data, so they should go away by themselves, except that the PDF may not have been created.

   Anyway, I will take a look at it today, and I will see if there is anything I can do to help resolve the problem.

   Did you create the 380 batch printers by hand? That must have taken a long time!

   Finally, here is one more thing to consider: if the PDF files are created automatically (via code), I would make sure that you control how quickly and how many print jobs you place in the queue to make sure you do not overload Windows and your PC.

Hi.

As you see from my list, some of the capture.exe processes are waiting for 50 hours. This does not seem to be a timeout ;)

We created printers manually gradually during a whole year.
 
The files are created by a special printing program of a LIS (laboratory information system). We do not have any source code, neither any ways of controlling how it creates print jobs.

Hi,

    Oops: yes you are right. Thanks for the additional info. I will run some tests here, and see what I can do to fix the problem.

    Cheers!
