Hi Ruben,
Below is the output of 'ps -ef | grep one' on a host that has been
disabled, rebooted and enabled. There are multiple versions of
collectd-client.rb kvm running.
We have discovered today a serious issue that is having an adverse
effect on our DNS system. When the machines below was enabled,
immediately our DNS server is flooded with requests from the host (see a
sample below).
Our logs show that this has only started happening since the
upgrade to 4.4. If we don't get a fix for this we will have to go back
to 4.2, which is something I really don't want to do.
Regards,
Gerry
