There have not been any changes that should require an upgrade since that was built.

There are a few things that can cause that message, including crosstalk with bitcoin. Do you run bitcoin as well?

Can you do something like

memorycoind getinfo | pastebinit
memorycoind getpeerinfo | pastebinit
tail -100 ~/.memorycoin/debug.log | pastebinit


or dpaste or whatever pastebin  util you use.

Then send us the urls you pasted that to?

We will be updating the linux builds later this week, but that should not be a factor for that message.
