SYMPTOMS
Services.exe may leak memory at a rate of about 40 MB per day. A Perfmon.exe trace may show the Private Bytes counter rising at a 45-degree angle. If you do not restart the server, the server may display an &quot;out of virtual memory&quot; error message.



CAUSE
Memory is being reserved for the NEWSTRING string variable and the \Arcname constant is prepended to a driver path and then checked for validity. The problem is that NEWSTRING is not freed with theLocalFree(NEWSTRING) command.
