Recreated using "tail /dev/zero" (consumes memory/ create oom)

++ ps -eo pid,ppid,cmd,%mem,%cpu --sort=-%mem

Following line changes in common_sls.py will fix this
1095 command = "ps -eo pid,ppid,cmd,%mem,%cpu --sort=-%mem | head|awk -F' ' '{print $1":"$2" "$3}' |tr '/' ' '|awk -F' ' '{print $1" "$NF}'|tr ':' ' ' | awk '{ print $3}' |grep -vE "CMD|sshd|ssh"|tr '\n' '^'"

1103 command = "grep -w %s /opt/ltp/runtest/*|grep -vE "grep|ssh|sshd"|wc -l" % boat
