Large number of "NET: Registered protocol family 30 31 36" messages
Issue
- On one of our VMWare guests, after updating VMWare packages we see a large number of following messages in
/var/log/messages
:
Jul 1 10:33:58 localhost kernel: NET: Registered protocol family 30
Jul 1 10:33:58 localhost kernel: NET: Unregistered protocol family 30
Jul 1 10:33:59 localhost kernel: NET: Registered protocol family 31
Jul 1 10:33:59 localhost kernel: NET: Unregistered protocol family 31
Jul 1 10:34:00 localhost kernel: NET: Registered protocol family 36
Jul 1 10:34:00 localhost kernel: NET: Unregistered protocol family 36
- Although occurrence of these messages does not impact the host performance, we would like to know what is causing such messages to appear.
