Hi,<div><br></div><div>We had a problem with our varnish server recently that sometimes the server will use all file descriptors available to it, which is set to 65536, and start refusing connections. I am wondering how to find out what's the real problem behind it. </div>
<div><br></div><div>The only thing I can think of is that I configured max_restarts=2 and we have 3 backends. When the the first backend returns a 404, varnish will try the second, and when the second backend returns 404 again, varnish will try the third one. Will this be a problem or cause any dead loops?</div>
<div><br></div><div>I would appreciate if anyone would shed some light on it problem. Basically when we encounter this problem everything seems fine and it is hard for us to diagnose the problem</div><div><br></div><div>
Thank you very much</div>
