Comment(by JakaJancar):

 I believe I'm getting affected by this. Varnish gets 100000 sess and
 sess_mem, at which point it's using 1 GB of memory and stops accepting
 most new requests.

 I'm getting 500 connections/s on on an 8-core HT-enabled machine and I get
 too 100k in ~15 minutes.

 Is this solved in 3.0? Will it ever be in 2.1.6?
