"AT" scheduler problems on Solaris 10 (Sparc 01 release)

Question

I am having a problem with 'at' scheduled jobs not running in Solaris 10.
When scheduling an 'at' job, I see the 'at' job listed with 'at -l', and the job does not run the script. .At the execution time, the job will not run and i still see the job listed in queue afterwards with 'at -l'. I have tested these on solaris 8 and another solaris 10 server and 'at' works fine without any problem at all.
Interestingly enough, 'at' jobs DO run correctly when scheduled in a cronjob, but not from command line. I have tried to make 'at' work with command line using differnet users and shells to no avail.
Here are two simple scripts I've created to show the issue.
# cat start_alert.sh
#!/bin/sh
at now + 1 min <<\EOF
./alert.sh
EOF
#cat alert.sh
#!/bin/sh
echo "AT Started the script" > /tmp/sh_status
Heres what happens:
app1# ./start_alert.sh
commands will be executed using /bin/sh
job 1152889697.a at Fri Jul 14 11:08:17 2006
(tried csh also)
app1# at -l
user = root 1152889697.a Fri Jul 14 11:08:17 2006
app1# date
Fri Jul 14 11:09:13 EDT 2006
app1# ls -al /tmp/sh_status
/tmp/sh_status: No such file or directory
app1# ps -ef | grep alert
root 11839 3520 0 11:19:30 pts/3 0:00 grep alert
Strange, as I said, i've checked permissions, tried different users and shells... Problem remains....
Anyone have any idea why this isn't working in solaris 10 ?

Hey
I actually found the problem,
I needed to
edit /usr/lib/cron/queuedefs
change contents to:
a.100j0n
b.20j2n90w
otherwise the jobs just queue and don't run even if I only start one ? Strange but it works!
