SYMPTOMS
An application that uses the 16 bit-subsystem (WOW) to call a 32-bit application repetitively will exhibit a memory leak. Memory is lost during this automated process and appears as a memory leak in Performance Monitor. This can be verified by monitoring MEMORY: Pool Paged Bytes, Pool NonPaged Bytes and Committed Bytes. Eventually the system starts to thrash for bytes to use during the process and appears to make no progress. In cases where the problem occurs on an NTFS partition, the following STOP message appears:
This problem does not occur when calling a 16-bit application from the 16- bit subsystem.
WORKAROUND
To avoid this problem, call only 16-bit applications from a 16-bit subsystem.
STATUS
