Comment 0 for bug 1365035

I've got this error a few times now with 1.20.6, and I don't think it's representative of an actual failure with the network. This is all on a private network that has been working fine before 1.20.6. Short paste here, longer paste attached:

If I had the option to leave the machine up (coming in 1.20.7+?) it would be helpful, since I can't repeat this every time.
