Hello,

MUMI is currently stopped, and the tail of its /var/log/mumi.log says:

Perhaps Ricardo or someone else has seen this error before?

I restarted mumi with 'herd restart mumi' on berlin, and it's working again.

Since Arun's commit 897967a84d3f51da2b1cc8c3ee942fd14f4c669b, Fiber is
not used anymore, so I'd hope the above issue vanishes.

Closing.
