Is user 'autosys' local and others ex: envadm, coming from LDAP or AD, and you use LikeWise or other software to authenticate these external users? Please check the /var/log/messages log from around the time the job terminates. It appears the auth software is intercepting the agent process (cybspawn) with a signal 6. I'd use strace on Linux to latch on to the cybspawn process id for the corresponding job and see where the signal 6 is coming from.
1. Start a 'sleep 100' job as envadm user.
2. Once the job goes to running, get the cybspawn process id (ps -fu envadm|grep [c]yb) for the job.
3. Execute, `strace -a -p <pid of cybspawn> -o /tmp/cyb.txt`
4. When the job finishes and terminates, the strace will exit too. Forward the /tmp/cyb.txt log to us for review.
Thanks,
