Several apps down after faulty automatic update to v8.3.2

[shrey]

After an (unexpected) automatic update to v8.3.2, most of the apps in my Cloudron instance are now in error state:

Error : Nginx Error - Error reloading nginx: reverseproxy exited with code 1 signal null

Additionally, the Event log shows this:

The CLI doesn't seem to help here either:

Rebooting didn't help as well!

1. Why was there no automatic rollback, when the update task failed?

2. How do i urgently fix this?

I just replied from support. To give more context from support, nginx restart has been failing on this server.

• What is listed in ulimit -a ? Mine says 1024
• You can try ulimit -n 3000 which increases the handle count. Does nginx restart after that?
• If that doesn't work either, can you reboot the server? Maybe this will free up some handles.

This got fixed after rebooting the server and repairing all apps. For some reason, the server ran out of file descriptors
