Thank you for all your replies. I've decided to patch the system and schedule
a reboot sometime soon which would destroy 241 days of uptime but then I have
never really understood what all the hype was about a box being up for so long
anyways :) A regular reboot (at most twice in 6 months) should be healthy for
the box.

The erroneous variables AGENTWORKS_DIR as well as CAIHPAD10 contain the wrong
substring path: "/CA" which it should contain "/ca".

These variables are in the INETD environment as mentioned by Darren Dunham but
I am not sure how this is gonna help since the app is not spawned from there.
However I should bounce the box after patching anyways since it's due for it.

The "$AGENTWORKS_DIR/scripts/envset" script does not contain any setting
related to the variables above and a grep on /etc/default/* comes up with
nothing.

Just a note to some people that the IF statement in the /etc/profile above
will only set a variable if the variable is initially blank but it is not
blank when /etc/profile is run therefore the inital incorrect value is
preserved.

Thank you all for your time and patience:
