<div>Hi</div>
<div>I'm using varnish-6.0.5,</div>
<div>1.</div>
<div>3nodes of varnish crashes every day and I should restart it else the whole of my system doesnt work anymore </div>
<div>I don't know the reason but my disks at that time shows that It has 50 MB/s (400Mb/s) Read and 48 MB/s write but my outbound network shows 120Mb/s</div>
<div>I put the link of Netdata picture at that time,</div>
<div>http://uupload.ir/files/c60r_varnish.png</div>
<div>How can I solve this problem?</div>
<div><br>
</div>
<div>2.</div>
<div>My next question is that I have another varnish that I set malloc to 68Gb (the server has 86 Gb ram) but it will pass 68g till 86 and server crash, Why does it exceed from 68g through I have adjusted the accurate and permitted number?</div>
<div><br>
</div>
<div>But really I'm confused and annoyed with first problem because it destroys my cluster</div>
<div><br>
