Hi Sharon,
Well, it seems to work on most platforms. There is no problem on about
30 different UNIX and Linux systems, and several of them are Redhat;
there are just 3 of them that don't change the user ID. I suppose I
can start looking in the code for the process service; I just hoped
maybe somebody had seen this problem before.
When/if I find the solution, I'll let the list know.
