Running multiple processes

James Williams

I have a program that monitors for new text files being saved in a folder. When it finds the file it reads it, writes the data to a SQL table, does some updates, then calls another program to print a report.

Then it waits for the next file.

Here is a copy of the code

System.Diagnostics.Process LOProc = new System.Diagnostics.Process();
LOProc.StartInfo.FileName = PSParmServicePGM;
LOProc.StartInfo.Arguments = PSGUID;
LOProc.Start();

After about a week the server becomes unresposive, I am assuming it is a memory issue. If I log out and back in and start my program is works for another week, then I have to do the same thing over again.

I ran processmon and I do not see the 2nd program getting stuck.

What is the proper way to call a 2nd program but not tie up the calling program waiting for the 2nd program to finish.

Can you try disposing the objects after calling the process?

No, the server is up to date.
It appears to be running out of memory after about of week of running.
The 2nd program is printing a Crystal Report and printing directly to the print server.
I just started watching the memory usage and right now it appears the splwow64.exe is growing.
When I opened it this morning it was 105,668 and now it is 113,984
My program was 14,424 and now it is 14,580
This is in the past 3 hours.

I don't know if the issue is in the way I am calling the 2nd program. I never clear or dispose of the process. It calls the 2nd program then waits to call it again. There can be several instances of the 2nd program running at the same time.

Did you check why the server is not responding? It might be due to some maintenance issue and it is not getting restarted.
