Comment(by bstillwell):
I'm also seeing this problem with varnish 3.0.2 on CentOS 6.2. There
isn't any panic output from varnishadm:
{{{
[root at den2tpv16 ~]# varnishadm panic.show
Child has not panicked or panic has been cleared
Command failed with error code 300
}}}
However /var/log/messages has some details:
{{{

The machine has 32GiB of memory with an SSD for storage (120GB OCZ
Vertex2). The storage option I'm using is: -s
file,/data/varnish_storage.bin,80G,32K
Using -s malloc,23G on this same box is quite stable, but I'm hoping to
start using SSDs to improve our hitrates (we have a very large set size).
