conflict with anti-virus program,
My anti-virus program is :ESET nod32 v3.0.
When I disable ESET nod32 v3.0, avarything is OK,system will not hang.
when you enable ESET nod32 v3.0,system will BSOD.

Especially when the File is large,for example, fileSize>10M .doc File.
(when fileSize is quite small,it is ok too)

Hi,my system is :Windows XP professional service pack 3

I suggest you use large size file,larger than 15M (especially microsoft Word .doc File) as a test File, it is easy to find something.

Do not use small size File.

Hi,I redo the test,maybe large FileSize is the major reason.

Small Size file is always normal even under running anti-virus program.
But if the FileSize is larger than 15M, something unnormal happan.

CallBackFileSystem has same problem.
It's random but often.
I guess, NOD32 is blocking App's thread and re-enter.
so it make system wide lock.

void Called_from_CBFS_proc(someArg)
{
Lock(needSyncForResource)
{
CreateFileAPI(something) <- NOD32 blocking this thread here
}
}

I guess you need to contact Eset with this.
