Flume server loss UDP packets

Flume server loss UDP packets

New Contributor

On one of the flume server I see a great loss of UDP packets at rush hour.

DNS server logs collected in syslog format on this server.
13% receive errors. "netstat -us".


OS - centos 6.6, kernel 2.6.32-504.el6.x86_64, 4G RAM, 2CPU(s)
load average 0-2, charge memory - 60% max, load network - 70% max.


I made to optimize the kernel sysctl.conf

these paramters are maximized
but % of "udp receive errors" does not change.
