Johnny,

You can use ExAllocatePoolWithTag to allocate memory and use tool
PoolTag from OSR website to monitor the memory allocation.

William

!poolused command in WinDbg. Be sure to assign sane tags to your
allocations.

For this command to work, you must set the GlobalFlag bit 0x400
(“enable pool tracking”).
This can be done manually in the registry, via GFLAGS tool or IIRC
Driver Verifier (which also has memory leak detector).
