Description Andrew Gormanly 2015-10-07 10:14:48 EDT
Description of problem: The system log is filled with many of these messages:

Oct  7 04:28:04 enterprise avahi-daemon[3780]: Invalid response packet from host

There is no useful purpose to sending this message to the log; it bloats the file and it obscures important messages.

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

How reproducible:
Every time

Steps to Reproduce:
1. Run RHEL5 on a network with whatever avahi doesn't like.

Actual results:
Many log messages.

Expected results:
One log message.

Additional info:
Seems avahi does not like Windows 10.  We have 1 Windows 10 test box, out of 500-odd machines, and it is triggering 20-25 of these messages per hour. There will be many more Windows 10 clients installed before our last RHEL5 servers get decomissioned, as roll-out is planned to start on 1st August 2016.

This bug is fixed in Fedora 21-23 already.

Easy fix, granting devel_ack+. But AFAIK there is no other maintenance release planned for RHEL5. I guess you should file a support case and request z-stream.

Red Hat Enterprise Linux 5 shipped it's last minor release, 5.11, on September 14th, 2014. On March 31st, 2017 RHEL 5 exited Production Phase 3 and entered Extended Life Phase. For RHEL releases in the Extended Life Phase, Red Hat  will provide limited ongoing technical support. No bug fixes, security fixes, hardware enablement or root-cause analysis will be available during this phase, and support will be provided on existing installations only.  If the customer purchases the Extended Life-cycle Support (ELS), certain critical-impact security fixes and selected urgent priority bug fixes for the last minor release will be provided.  For more details please consult the Red Hat Enterprise Linux Life Cycle Page:

This BZ does not appear to meet ELS criteria so is being closed WONTFIX. If this BZ is critical for your environment and you have an Extended Life-cycle Support Add-on entitlement, please open a case in the Red Hat Customer Portal, https://access.redhat.com ,provide a thorough business justification and ask that the BZ be re-opened for consideration of an errata. Please note, only certain critical-impact security fixes and selected urgent priority bug fixes for the last minor release can be considered.
