--- Comment #1 from Jilles Tjoelker <jilles at FreeBSD.org> ---
It is expected that ps (or any other tool that lists processes) does not show
the command line if it is longer than the value of the kern.ps_arg_cache_limit
sysctl (default: 256 bytes) and the process is swapped out.

A proper fix is not easy (this would involve not relying on the process list).

Apart from the workarounds mentioned in bug #221518, it is possible to increase
the sysctl or move configuration data from the command line into a
configuration file (if supported by the daemon).
