I do think so:

(1) The child isn't segfaulting -- it's dying with signal 3 (SIGQUIT),
and only after the parent sends SIGKILL.

(2) I have already increased cli_timeout and decreased the maximum
number of threads, and it's not helping.

(3) The number of threads at the time that the child dies is not high.

After switching to malloc and increasing the cli_timeout, Varnish does
stay up for longer periods of time, but it's still dying at least once
a day.

I'm not.
