If you manage many objects with high traffic , Varnish get a swap (although it rare)<\/p>\n

Varnish 3 have new parameter “shortlived”.
\nThis parameter description is<\/p>\n

Objects created with TTL shorter than this are always put in transient storage.<\/p><\/blockquote>\n

transient storage is malloc storage.<\/p>\n

\n\r\n\r\nstorage.list\r\n200\r\nStorage devices:\r\n        storage.Transient =*** malloc ***\r\n        storage.s0 = malloc\r\n\n<\/pre>\n
<\/p>\n
Question <\/h3>\n
How much use memory to this settings?<\/p>\n
\n\r\n-s malloc,100M\r\n\n<\/pre>\n
Answer<\/h3>\n
All your memory are belong to us.<\/p>\n
If your sometimes use transient storage, memory does not swap.
\nBut, unlimited is disgust.
\nLet’s limit the transient storage size.<\/p>\n
\n\r\n-s Transient=malloc,100M \\\r\n-s malloc,100M\r\n\n<\/pre>\n
This settings is limit to transient storage size to 100MB<\/p>\n
note:<\/strong>Do not only transient storage settings, is an error.<\/p>\n
\n\r\n**request 57 MB file 10 repeats\r\n  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND\r\n12011 varnish   20   0  860m 599m 1184 S 62.4 29.9   0:18.33 varnishd (unlimit)\r\n12083 varnish   20   0  354m  93m 1208 S  0.0  4.7   0:04.18 varnishd (limit)\r\n\n<\/pre>\n
note:<\/strong>Don’t you set to storage size below your one contents max size.
\nIf contents size is over the storage size, is 503 error.
