System locks up after a day or two
I'm finding that my server was going weird after a few days running after upgrading to F25. It runs Kodi all the time, and Owncloud, and MythTV, with some software RAID.
Anyway, I am finding that Kodi was still working, but SSH attempts would prompt for a password, then hang. I could get to some sort of BASH prompt with ctrl+c, but trying to run any programs, even top, would hang.
If I exited Kodi, everything would hang. If I tried to reboot the system, it would hang.
I wanted to try and search the system for zombie processes to see if there were no more free process IDs?
I don't think it was MythTV that caused it, as it still happened with that stopped.
I'm now running on Xorg, it still hangs.
I've updated to the latest Kodi and MythTV releases and it still does it.
How can I work out what's killing the machine?
