sleep command memory violation using parallel

[Mauro Tridici]

Dear Users,

checking the operating system (CentOS 7.2) audit logs, I detect a lot of "sleep 
command memory violation".
I investigated about this issue for almost a week and I think I found the cause 
of the error message mentioned above.
It seems it is related to the "parallel" command usage and I'm able to 
replicate the problem as follows.

Could you please help me to understand what I'm doing wrong and how to fix this 
issue?

ARGUMENTS FILE:

cat test
echo 1
echo 2
echo 3
echo 4
echo 5
echo 6
echo 7
echo 8
echo 9

PARALLEL VERSION:

parallel --version
GNU parallel 20240422

HOW TO REPLICATE THE PROBLEM:

parallel -j 1 < test
1
2
3
4
5
6
7
8
9

ISSUE DETECTED IN AUDIT.LOGS:

type=ANOM_ABEND msg=audit(1714688507.057:173872): auid=0 uid=0 gid=0 ses=23831

Thank you in advance,
Mauro
