[lvs-users] Load balancing tftpd stops after a while
Thanks for reading. First post, new to LVS, I've gone through the
introductory docs, I've inherited this service
configuration file:
http://pastebin.com/XrNbGR7Q

ipvsadm --version
ipvsadm v1.26 2008/5/15 (compiled with popt and IPVS v1.2.1)
on Redhat 6.5

We're balancing a tftp service it was working fine, until recently it
began stopping balancing at seemingly random times, if we do a service
pulse restart, the balancing starts working again, I think this is
related somehow to the well known "ARP Problem", the symptoms are very
similar but I don't really understand it nor how to fix it, I'm not a
networks guy but I'm entitled to keep track and try to fix this issue.

the redhat guys aren't helping much.

Any ideas?



Thank you very much and greetings from México City.

Sorry, I wasn't precise, not only stops balancing, stops sending traffic
entirely.
Thank you again.

Can you be more specific? Right now I am assuming you mean the
director node is not sending any tftp traffic to any of the real
servers.

When this happens, what is it output from ipvsadm? Is the VIP still
present on the correct interface? Are pulse, lvsd, and nanny all
running on the master (before you restart pulse)?

How did you choose to solve the arp problem?

First I have heard of this.
