Help needed with gopacket/pcap concurrency issues.

<p>I&#39;m working on a project that requires me to run two concurrent goroutines that listen on two different network interfaces and capture all traffic that passes through them. However, I&#39;ve noticed that after about 200 successful packet captures, my program stops capturing with no errors to be seen.</p> <p>My initial thought is that a deadlock is being created somewhere within the included gopacket/pcap libraries. Any thoughts/suggestions on this are greatly appreciated. </p> <p>Thanks.</p> <hr/>**评论：**<br/><br/>bradleyfalzon: <pre><p>Without seeing the source code, I can&#39;t help too much but provide you with an example on how I&#39;m doing something:</p> <p><a href="https://gist.github.com/bradleyfalzon/1d05d490e4f8b1708d866e3660ed7b11" rel="nofollow">https://gist.github.com/bradleyfalzon/1d05d490e4f8b1708d866e3660ed7b11</a></p> <p>This is some old code so I&#39;ve changed my style slightly, but when the application starts, it starts a single listener and processes each specific packet in another go routine.</p> <p>It&#39;s not quite similar, nor do I think it&#39;ll help too much.</p> <p>But I think what you really need to do is start paring the issue back and making it simpler, does the issue happen in one thread? etc etc</p></pre>ymmit987: <pre><p>I&#39;m not sure why this was the solution, but after I kicked off my two main goroutines in my main() func, I started an infinite for{} loop to keep the program from closing. Instead I changed it to a select{} on a whim and it solved my problem of the program hanging after a seemingly random amount of time. </p></pre>bradleyfalzon: <pre><p>Interest to know and yeah, select{} sleeps whereas for{} spins.</p></pre>
