Hotfix v5.15.3 (#5150)

The original configuration used the default `min_procs=<max_procs_value>`.
A recent change set this value to zero, but a lot of systems started to
receive error messages about the socket file and in some systems lighttpd
wasn't able to restart the PHP process, returning HTTP error 503.
Setting this to 1 fixed those errors.
