Description Kaleb KEITHLEY 2017-05-31 15:33:51 UTC

Description of problem:

portblock monitor() is "flooding" /var/log/messages like

   notice: vip1_unblock_monitor_10000:16295:stderr [ 0+0 records in ]

and

   notice: vip1_unblock_monitor_10000:16295:stderr [ 0 bytes (0 B) copied, 0.139558 s, 0.0 kB/s ]

End users (customers) are asking if it's safe to ignore these. I told them it is safe, but it'd better if they weren't there at all. They don't seem to be telling them anything useful.

Version-Release number of selected component (if applicable):

resource-agents-3.9.5-82.el7_3.9.x86_64

This can be ignored.

We might want to supress these, as they're not relevant for the user.

qa-ack+: portblocker agent should not be excessively logging
