Loss of plugin configuration data

I’m having some problems with my Vera 3.

A few days ago I noticed that Homewave had reverted back to a version of my iPad GUI and that I’d lost several iterations of changes. The changes had been saved and used for several days. I’d noticed this problem on a small scale several months ago but didn’t do anything about it.

Then, earlier today, I received a massage from Datamine that my Vera had restarted and that I needed to reload the graphing GUI. When I did that Datamine was showing that I only had 2 graphing channels rather than ~19.

So… I suspect something is causing my Vera to crash and restart, which is then causing certain plugins (eg, Homewave and Datamine) to lose their configuration data.

Has anyone seen similar behavior before? It’s driving me nuts!
