When I install customized RHEL 6.5 with no GUI, on the Virtualized Platform like Esx Server. I am constantly getting, kernel message netlink: 12 bytes leftover after parsing attributes.. And this message is dumped into the /var/log/messages file. But When I install RHEL 6.5 without any customization, and select minimal during package selection. I am not getting this kernel message at all.

What could be the problem?

As per RHEL 6.5 documentation: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/6.5_Technical_Notes/net-snmp.html

The RHEL6.5 has fixed this issue in BZ#927474. But How it is related to net-snmp is not clear?

As when you install RHEl6.5 with/without snmp package it doesn't give any kernel error message?

But when I install the customized RHEL6.5, with selected set of packages, It starts dumping the error message.

Moreover from the RHEL documentation link If the fix is required in net-snmp daemon, then it should always be running, which is not the case, when you don't install the net-snmp package itself. And Still we don't get the kernel message.

Any pointers to solve this, would be a great help!

Here is explanation from kernel developers.

  • I don't have the kernel source code. So I can't comment whether the RHEL 6.5 have implemented it or not. Moreover It doesn't solves my problem. Appreciate the link you shared. – kvivek Feb 17 '16 at 14:39
