SYMPTOMS

A memory leak may occur in SNA Server's host print service when it closes connections to physical printers. This was observed while performing stress tests on the host print service while simulating a network error to the destination Windows NT printer. This problem may occur when using either 3270 or 5250 print emulation.

CAUSE

The virtual print driver used by the host print service was not properly releasing memory that it allocated for an internal printer information structure.
