Still Getting 'Too Many Open Files' Error on Ubuntu VPS After Adjusting Ulimit: What Am I Missing?
0
I'm desperately seeking help again on the 'Too Many Open Files' error on my Ubuntu VPS. I posted before and received some great advice, which I diligently followed, but I'm still hitting this wall and it's driving me absolutely insane. My Node.js app keeps crashing, and Nginx occasionally throws errors, all pointing back to this dreaded file descriptor limit. Iโve been trying to get these file descriptor limits sorted for hours now, and I'm just completely stuck. Here's what I've already done:
- Increased
ulimit -nin/etc/security/limits.conffor my user and globally. - Set
fs.file-maxin/etc/sysctl.confand applied it. - Checked and modified the
LimitNOFILEdirective in mysystemdservice unit files for both Node.js and Nginx. - Restarted everything multiple times, even the entire VPS.
ulimit that I'm overlooking, especially when dealing with modern web applications? I really need an expert to chime in before I pull all my hair out. Waiting for an expert reply.2 Answers

/limits` to confirm the effective `system resource limits`. What do the `Max open files` values show for your application processes when they're under load?
It's like the changes aren't sticking or there's another hidden layer overriding everything.I've definitely been there; this issue can make you want to throw your monitor out the window, especially when you're trying to keep those ad campaigns running smoothly. Beyond the usual `systemd` and `sysctl` adjustments for `server configuration issues`, ensure `pam_limits.so` is correctly loaded in `/etc/pam.d/common-session` and verify the *actual* limits for your running Node.js and Nginx processes using `cat /proc/
