SYMPTOMS
Your Windows NT computer configured with QMS's spooler exhibits RPC errors and other low memory errors.



CAUSE
The QMS spooler monitor does not deallocate memory correctly. PoolMon shows an increase of about one handle per print job. This is because the thread is not discarded correctly when a print job is sent to a QMS printer. Because this is a monitor, which is loaded when spooler is run, it does not exit while Windows NT is running and over time your computer slows down and exhibits errors.

NOTE: With pool tagging enabled and a debugger attached, the number of "THRE" tags steady rises. This directly relates to the thread objects left stranded by the QMS DLL.



RESOLUTION
QMS has a fix for this problem in the latest version of the QMS monitor. Please contact QMS support for the fixed driver.

You can also use LPR in place of the QMS monitor. QMS does contain some extra features such as enhanced status messages from the printer and accounting information on the printer use.
