Re: [users@httpd] apache 1.3.33 multiple instances problem

Hi Joshua,

Found out that for solaris, use the truss command instead of strace so I
ran the truss command (see below):

itisgrp@itis-appdev bin]$ truss -o /tmp/output httpd start
Starting the able Apache web server

This is in regards to not being able to start up the 1.3.33 apache as a
non root user.
I can start up this apache as root for multiple instances but I can't
start it as a non-root user??

I've verified that the port is above 1000 (for a non-root user)
I've verified that the script which calls the httpd command uses the -f
to specify different config files for each instance (one for able and one
for fad)

I'm stumped as to why I can start up 1.3.33 as root and be able to start
up multiple instances, but it won't start up for non-root user
itisgrp??
