Running IC reports for one of our companies never finishes

SUGGESTED

We are running our end of the month reports, and for one of our companies running the On Hand Detail Report never gets past the generating stage even if we let it sit for hours. The specific task "TASK####.exe" has a constant network usage so something is happening, but it will never fully finish generating. So far this is the only module we are having issues with. Have tried restarting the server but still having issues. Any idea what could be causing only this report to never be able to finish?

Thanks
