i am seeing this messgae swith Qlogic as well as Emulex HBA while running IO with NETAPP filers.
i am seeing some significant IO delay at the time when it displays these messages.

i am running test with RHEL7.3 SnapShot2/SnapShot3.

can some one explain me what these messages mean?
does it have any thing to do with IO delay?
