I had a sick setup going, then one day the web interface stopped responding. I waited two weeks to reboot because it meant no plex for a while. Here's what I've done:

 

I formatted a brand new flash drive and re-imaged it with the same version of unRAID (5.0-rc8a), copying only the contents of the "config" directory to the new flash.

 

starting a emhttp manually, as expected, causes a segmentation fault right away.

 

 

Below is some debugging after a reboot:

I think its REDICULOUS there is no way to cleanly reboot a system through CLI, i'm having to "shutdown -r now" and hope the parity drive isn't messed up..

 

Any ideas? I think I'm going to get this guy up and going again without emhttp for now, but please give me guidance for the next brief time i have to troubleshoot.

Still no update on this.. i rebooted once and the web interface came back up about 30 minutes later.. stayed online for a few hours and is now offline. I can't just keep rebooting. Why is this happening?

Attach a syslog.
