Hmm, that trace looks normal to me. It doesn't look like it's
busy-looping, as I would expect if it's using 100% of the CPU.

Can you post the full log, or at least a larger chunk? I don't need the
data in the quotes from read() and sends() that you removed, but I would
like to see the trace from a longer period of time to see what the
pattern is.
