[Dxspider-support] Help & Questions

[Bill Shell]

Ed,
Ed,
Your comments of /spider/perl/cluster.pl running as root is wrong. Your 
dxspider process configuration file /etc/init/dxspider.conf should 
define the run levels and owner of the process.  In the example you 
gave, it has /spider/perl/cluster.pl running as a process as sysop.
