Payment engine error

[etherunit]

Got this shortly after upgrading to 0.46.x. There were some "timeout waiting for reply to "p2p-keepalive": p2p send timeout" messages above it. Possibly related to payment engine error error="sending of invoice failed: did not sent a new exchange message"

panic: close of closed channel
