The cause is here:
pselect6(22, [4 7 8 21], NULL, NULL, {10, 0}, {[], 8}) = 1 (in [7],
left {9, 999997763})
recvfrom(5, 0xad9330, 18780, 0, 0, 0)   = -1 EBADF (Bad file descriptor)

It is waiting for descriptors 4,7,8,21 and then receiving from
descriptor 5. That is an issue it should now be fixed in the
repository.

What I don't understand though is how it does get into an infinite
loop. All the callers of recvfrom() check for its return code. I will
check again later with a more clear head.
