Also, what was the status of C2 when you checked for these writes? Do you have the output of echo "stat" | nc localhost port? How long did you wait when you say that C2 did not received the writes? What was the status of C2 (again echo "stat" | nc localhost port) when you saw the C2 had received the writes?
