Lots of logging when using OpeniSCSI

[E_Mouws]

Hi,

we're using Proxmox 5.3.5 and connected it over 2 x 10GB to a EMC VNX5300.
we see al LUN's presented by the EMC and the LUNs can be used by VM's running on our proxmox cluster.
But in de syslog of the hosts using the EMC we see a lot of kernel messages recurring approx each 20 seconds:

Is this indicating an error or informational, or is it caused by the multipathing-setup and how can we configure it to be more quiet ?
