Thanks for sending this in.

I think that signal 25 on the system you describe denotes an
excessive file size (SIGXFSZ) -- so it makes sense.

Having the pqact(1) utility have its own logfile must be an NWS
thing: as far as I recall, we don't have any examples of that in
our documentation and the prototype LDM configuration-file in the
distribution doesn't have that.  All of the LDM systems with which I'm
familiar (admitedly, not all that many) mix pqact(1) log entries with
the rest of the LDM log entries.
