Comment (by numard):

 Hi Martin,
 I've had this in production for a few days - not great results I'm afraid.
 Tried the 3.0.3-plus branch, as well as 'persistent'. Crashes still
 happen, though not exact output in panic (as expected).

 From branch persistent, panic is :


 {{{
 Last panic at: Mon, 22 Apr 2013 01:40:53 GMT
 Assert error in smp_appendban(), storage/storage_persistent.c line 98:
   Condition(4 + sizeof t + 4 + len < left) not true.
 thread = (cache-main)
 ident =

 }}}

 from 3.0.3-plus, almost identical to previous,

 {{{

 I'm building on up to date Precise 12.0.4 LTS, with nothing special :

 {{{
 ./autogen.sh
 ./configure --exec-prefix=/usr
 make
 make install
 ldconfig

 }}}
