Do NOT run UV processes directly from cron without using PHANTOM!!
When run from cron, uv processes get the same group process id. That
id is used to determined the printer memory segment used. So if you
have two uv processes that kick off and are running at the same time,
they are using the SAME printer memory segment. This segment
contains, among other things, the MFILES buffers. The summary version
is that these multiple processes can then start stepping on each
other's uv files causing file corruption and data loss.
I had this happening with a client just last year.
