varnish consuming too much memory?

[Jodok Batlogg]

hi,

i'm wondering how varnish determines how much memory it should  
consume...
we're running multiple varnishes on one box and now and then one  
instance starts to use more and more memory.
right now it's using 65% out of 16GB ram, which is pretty much :)

varnishlog shows that pretty much traffic is going on :)
varnishhist shows that the requests are beeing served really fast
varnishtop shows: the following:
