Who Me Too'd this topic

We've installed MM on Ubuntu 14.04 and everything starts and seems to work OK initially.

However, after a period of time it seems tro crash.  Not really sure how log, but as an example I booted yesterday used if fine for an hour or so, and this morning it had failed. 

A typical error (top right in red box) would be ERROR RETRIEVING MINEMELD CONFIG: Internal Server Error. - see screenshot attachment.

If I restart the minemeld service everything starts and all is good again for a period of time.  Nothing jumps out in the logs - is there any advice you can give on things to check?

Thanks
