Subject [Bug 53579] httpd looping writing on a pipe and unresponsive (httpd <defunct>)

--- Comment #8 from Loic Etienne <loic.etienne@tech.swisssign.com> ---
We observed that some processes try to read from the pipe of death from the
file descriptor 0 (instead of 7 on our system, from which other processes read
the pipe of death).

dummy request read from file descriptor 0
dummy request fails (no ssl)
file descriptor 0 closed
read from file descriptor 0 (instead of pipe of death), error bad file
descriptor
loop to the next connection

Note that the correct file descriptor 7 is open in the child process in
question, but the variable supposed to store it contains 0 instead of 7.

We also observed that all our processes are gradually affected by this problem,
but we have no hypothesis what event triggers this dysfunction.
