If I'm seeing intermittent (not consistent) "operation not permitted" errors when trying to start a script, what is a likely cause of that? Could it be, perhaps, that there isn't enough memory to load the kernel module?
I see things like this:
Error inserting module '/scratch/tmp/stapHHzQ11/stap_25086.ko': Operation not permitted
Error, 'stap_25086' is not a zombie systemtap module.
Retrying, after attempted removal of module stap_25086 (rc -5)
Error inserting module '/scratch/tmp/stapHHzQ11/stap_25086.ko': Operation not permitted
Pass 5: run failed. Try again with another '--vp 00001' option.
Thanks,
Nick

Does 'dmesg' give any hints? Can you paste somewhere output from
stap-report? Does 'sudo modprobe SOMETHING_ELSE' work for you in
general?
Could you be experiencing https://bugs.launchpad.net/ubuntu/+source/systemtap/+bug/1054274?
