What does the number on the end of the [flush] thread mean?
Issue
- ps command shows some processes named like [flush-x:x]
# ps aux | grep flush
root 531 0.0 0.0 0 0 ? S Mar06 0:00 [flush-253:1]
root 7479 0.0 0.0 0 0 ? S Mar06 0:00 [flush-253:2]
- What do those processes actually indicate and represent?
Environment
- Red Hat Enterprise Linux 6
