Added socket timeout. Turns out that the device <img class="emoticon" src="https://pfspipe.ipmu.jp/jira/images/icons/emoticons/help_16.png" height="16" width="16" align="absmiddle" alt="" border="0"/> is usually fine, but sometimes the send() system call does not return, even when the socket is new and the buffer must be empty. Odd.</p> <p>Merged at b0c596a, tagged 1.1.2. Running at Subaru.</p> <p>The send() fails by blocking about half the time. This fix keeps the actor running, but cannot fix the controller/link problem. Should look carefully at the tcpdump traces, but I have not done so.</p> Development Rank 0|zzstnz:
