<div dir="ltr">Hi,<div><br></div><div>Varnish uses a memory-mapped file to store its data. Therefore, it is expected to use a lot of memory. However, when the kernel gets low on memory, it will push memory-mapped back to disk. This is similar in mechanism to the kernel's disk cache.</div>
<div><br></div><div>Does anything indicate that the memory pressure is actually the problem?</div><div><br></div><div>Perhaps try lowering the maximum number of threads. Also, perhaps try making the varnish cache file smaller.</div>
<div><br></div><div>Hope this helps.</div><div><br></div><div>- Leif</div></div>
