Max Memory for a User

[tbutler]

It seems as though cPanel limits all shell users (other than root) to using just 200 mb of RAM for a process (according to ulimit's max memory), which is causing "Out of memory!" errors on a script I'm trying to run that is multithreaded. Is there a way to change the limit for a particular user?

(The context: I have a Perl backend to one of my web sites that does a bunch of updates via multiple threads. Perhaps the version of Perl or the libraries it uses are somehow smaller on my old CentOS system, but on the new AlmaLinux server I put it on, it seems to need about 300-400MB of RAM to operate its four threads without running out of memory. It runs fine as root, when there are no limits on it.)

Hey there! Do you have fork bomb protection enabled on that machine? If so, can you try temporarily disabling it to see if that resolves the issue?

Thanks @cPRex! I did try disabling it and didn't notice a difference. I only left it off momentarily -- does it take awhile to "take effect"?

No, that would be an immediate change, but you'd have to re-login as the user to ensure you're getting a new session with that change in place.
