500 Internal server error

[Laserbait]

Yesterday I was working in the GUI of my RN204 just fine.  I changed the retention policy on my volumes from the "smart", to 3 days, and quit.

Today, I can't access the array GUI.  It's reporting a "500 Internal Server Error".

I am able to log into the CLI, and it seems to be up.  did a df -h, and none of the mount points are full.  

I tried to download the logs with RAIDar, but it won't accept the password (same username/password for the CLI works fine).  It's running ReadNAS 6.10.4.  I have not tried to reboot it yet,  just in case it doesn't come back up.

It's only my ReadyDR target, so I nuke it without loosing any data, but would prefer to fix the issue, as resyncing it with my 316 will take days to complete. 

What logs can I look at to start to figure out what happened to this thing?
