Hi Xuejing,<div>Its hard to provide any suggestions without more information. We have been running 2.1.5 on multiple sites with a fair amount of traffic and have not had any stability issues.</div><div><br></div><div>It might help others provide you with some suggestions if you include the os / distro you are running on and the output of varnishstat -1. Please also provide a little more information about your environment-- ie what is varnish connecting to and do you have anything between varnish and the client.</div>
<div><br></div><div>What are your backends doing when varnish hangs? Are they responsive?</div><div><br></div><div>Damon<br><br><div class="gmail_quote">2012/2/2 xuejing <span dir="ltr"><<a href="mailto:xuejin3@staff.sina.com.cn">xuejin3@staff.sina.com.cn</a>></span><br>
