Today I ran into a problem with PT Magic (PTM) that the inotify limit was reached on Ubuntu. Inotify (inode notify) is a Linux kernel subsystem that acts to extend filesystems to notice changes to the filesystem, and report those changes to applications. Just as a future reference for myself and as a reference to others a very quick write up how to solve this.
You can get your current inotify file watch limit by executing:
$ cat /proc/sys/fs/inotify/max_user_watches
You can set a temporary new limit with:
$ sudo sysctl -w fs.inotify.max_user_watches=16384
If you like to make your limit permanent use:
$ echo fs.inotify.max_user_watches=16384 | sudo tee -a /etc/sysctl.conf $ sudo sysctl -p
That’s it. The problem should be solved. At least this is the workaround. I have submitted an issue to TP Magic so that they can fix it properly. We will see.

Hey bud, I see you posted on PTMagic’ s github page 2 days ago. Have you heard anything from them yet or have figured out a fix yet?
This is the fix as long as they do not fix PTM. Have you tried it?
No actually, I saw this and was worried to run it on my VPS. I was just wondering if there was a permanent fix yet or that you had figure out something.
This is it 🙂
