Too many open files

[radomirpolach]

There is similar post for original FreeNAS on BSD: https://www.truenas.com/community/threads/too-many-open-files.53996/

I have this error when starting Kubernetes applications and sometimes when starting middleware. How can I increase this, it may be the reason why I have so many weird issues.

Did you find any fix for this? I've just had this happen once so far as I've added a bunch of new applications to my SCALE server.
During startup of an application I get:

Code:

[custom-init] No custom services found, skipping...
failed to create fsnotify watcher: too many open files

Edit: I had a lot of disk activity at the time probably. The application was stuck on deploying for quite a while but eventually succeeded, presumably as file handles freed up.

Yes I set sysctl parameter:

fs.inotify.max_user_watches

4962130

Yes I set sysctl parameter:

fs.inotify.max_user_watches

4962130

Even with this parameter set, I still get the error.

You might get into another limit in this sys group, here is what worked for us:

Code:

fs.inotify.max_user_watches = 699050
fs.inotify.max_user_instances = 10922
fs.inotify.max_queued_events = 1398101

Here is a script to calculate them keeping in mind the maximum RAM usage.
