what OS / SP are you using?

W2K3 (5.2) SP2


Are those strings within your TSP code?

They're in the SVHOST process "somewhere" - hard to say who owns the blocks
of memory that contain them.


How exactly did you notice the mem leaks?

I wrote a little app to monitor our TSP's internal tables, and I included
memory size as part of the ouput. The damn thing just grows inexorably as
calls come in. I've looked at the obvious "news" and "deletes" in our TSP's
code, but they seem to pair up OK.


Is there any pattern on when they occur?

Not that I've found.


Just searched Windows source code (XP/SP2) but didn't find any occurences
of
"ASYC" or "LMEM" in TAPISRV specific files.

I looked at our source code and didn't find any either! Google wasn't
helpful either.


Brendan,
I just searched WS2k3/SP2 sources:

LMEM occurs in:
- /base/win32/client/ as UNICODE string; there is also a lmem.c file.
- /admin/pchealth/sysinfo/msconfig/ but not as string but only as long lMem

ASYC occurs in:
- /printscan/ui/printui/ as a SIGNATURE string.

Doesn't seem TAPISRV related.


Maybe adding _CrtDumpMemoryLeaks() to a _DEBUG version of your TSP may be of
any help.
Please see MSDN for details.
