 Hi,

 While stress testing persistent storage (around 300req/s, 99% miss), I get
 regular panics, from every minute to every 5 minutes depending on the
 storage type (local disk, nfs).

 Assert is the following :


 {{{
 varnish> panic.show
 200
 Last panic at: Wed, 09 Apr 2014 11:56:57 GMT
 Assert error in smp_oc_getobj(), storage/storage_persistent_silo.c line
 437:
