Thank you for you reply.

I had a response from someone on CServe as well regarding this.  I was about to
abandon all hope.  I was going mad trying to find a bug in my code. I knew it
wasn't an access violation, wasn't the stack or anything like that because thos

things get trapped.  I was looking for subtle abuses of the API calls that I
have found to corrupt the system before, but I find nothing here.  I suppose
those 100 lines of code were a desperate act. 

Have you ever noticed that iterated calls to DosCloseNPipe with an invalid
handle will trap the whole system after about 70 iterations? That one was hard
to catch too, but at least it didn't kill the debugger while I was trying to
trace it. I discover it one day when a server was down and my client app was
trying to open the pipe.  DosCloseNPipe was being called even when
DosConnectNPipe failed. I carelessly ignored the return code from the close and
never noticed a problem figuring it would just return a harmless
"ERROR_BAD_HANDLE" anyway...

I learned a valuable lesson with that problem and was looking so hard for
something similar in the code with the find first problem. I was looking so har

I didn't even think of blaming the system .

I am happy to report that since installing 7045 (& fix to NET.EXE) it is lookin

stable now. The swapper never gets larger than 4MB on the 12MB machine. It used
to get up to about 7-8MB before it hung.  Seems clean now.
