Thanks. Was looking in the wrong place (cmd switches).

Is there no way to spawn a completely fresh cmd instance?
I wouldn't have a problem utilizing temp files to pass on the few select variables that have to be kept.

What is the syntax for the start command to launch cmd.exe in a way where only specific variables are retained? Example: set "VariableThatsSupposedToBePassedOn=X" set "VariableThatsNotSupposedToBePassedOn=Y" start "" cmd.exe "set "var=%VariableThatsSupposedToBePassedon%" & echo "%var%" & echo "%Vari...

Never mind, the solution was on the first page. I just put timeout /t 1 in my cmd.exe spawnloop.

By the following link you can find the long discussion how we tried to fix it. https://www.dostips.com/forum/viewtopic.php?f=3&t=6133&hilit=cmdpid Before I dive in, did you find a solution or not? In my case, the total number of maximum parallel JREPL calls is fixed, so in theory I could give each ...

I ran across a strange problem when running multiple looped batch files in parallel that all execute (individual copies of) JREPL. C:\Users\Vini\AppData\Local\Temp\jrepl.bat.14.06.2022_ 2.21.56,50_27286.temp"\\"!")" kann syntaktisch an dieser Stelle nicht verarbeitet werden. This is a nonsense error...

Hmm, ok. I thought there maybe is a native way in batch because findstr can process the whole file way way faster than a for /f readloop.

I have a very large text file that I need to split at a certain line number.
Can this be done without having to for-loop through all the lines?
I'm open to external utilities.


Unrelated question: Does using unnecessary delayed variables (! instead of %) significantly reduce speed?

I was busy with other stuff but I will probably not bother finding the exact cause since I was planning on reinstalling my OS anyhow. Also, I am pretty certain that with the tipps provided here and some other simple optimizations to the code, it will be possible to avoid these memory-hungry loops/co...

Ok, going to start rewriting my program then.
Learning a lot here, thanks again!

Ok, I will test that. How does CMD work out piping internally or more specifically, what counts as a "critical pipe" capable of causing memory issues? Is it just piping into a command (with "|") or does it apply to "redirecting" in general? For example, could I avoid the problems by writing to tempo...

Just Windows defender.

Ok.

Is it only the nonpaged pool that can cause a system crash or does this also happen when memory is low in general? In other words, is it enough to only monitor the nonpaged pool in the batch file?

What kind of memory % do you suggest for stopping the program?

Yes, that's the one I am using.
More specifically: dir /s /a /n /tw /o-d /4 /-c

Thanks for the tips!

I think the leak is coming from some driver. Deactivating the antivirus gives the same result.
So there is really no way to clear the nonpaged pool manually?
