Brief description of the problem
All pages (dashboard, storage, system, etc.) Are unable to display with the ‘Houston, we have a problem’ error.
Detailed step by step instructions to reproduce the problem
Using multiple browsers on same local network as Rockstor NAS attempt to hit any page.
I think it’s the Unifi rock-on … it’s using an insane amount of files (it looks like the process is bouncing but not cleaning up after itself…)
[root@rockstor ~]# lsof | grep unifi | wc -l
