By the looks of it, the child is killed of because it's unresponsive, and
it seems to me that it assert-error in the child is a result of this.

Have you tried simply increasing the client timeout? (-p cli_timeout). The
default is very agressive, and I've seen it kill off healthy childs that
are bussy delivering content even with a cli_timeout as high as 21 seconds.
Definitely something to test at least.
