Assert on latest trunk 3233

[Audun Ytterdal]

I was trying to upgrade from 3120 to 3233 for one of the varnishes in
front of vg.no

Crashed every second with the following assert

Sep 28 12:22:32 sol varnishd[20950]: Child (27902) said Child starts
Sep 28 12:22:32 sol varnishd[20950]: Child (27902) said Ready

d6ac00 {     },     vcl = {       srcname = {         "/etc/varnish/vg.vcl",
     "Default",         "/etc/varnish/identity.vcl",       },     }, },
Sep 28 12:22:32 sol varnishd[20950]: child (27909) Started

reverted back to 3120 and it works again.

Centos 5.2 and following parameters

/usr/sbin/varnishd -a :80 -f /etc/varnish/vg.vcl -T 127.0.0.1:82 -t
120 -u varnish -g varnish -p thread_pool_add_delay 100 -p
thread_pool_timeout 600 -p client_http11 on -p lru_interval 3600 -w
10,1000,120 -s malloc,7G -P /var/run/varnish.pid

(are those still valid performance tuned parameters...?)
