High delay between accept'd and processing

Hi all,

We're doing some tests with Varnish, and I'm trying to understand some timings.

With a very low traffic (<5 req/sec), I got sometime a delay of several *seconds* in the fourth number of ReqEnd [1].

For example, if I parse timings for only one RxURL and filter values by HIT :
minimal value : 0.000062704 s
maximal value : 5.040635347 s
average : 1.50531 s
number of requests : 300

Someone has clues to help me to understand what's going on? Maybe some specific varnish or linux stats to check ?
