I think I may have found my cluster issue in regards to the failover not
working correctly. The throughput issue seems fine now with the additions and
running on a single LB for the last week and a half has proven that the system
works correctly.
What I noticed today is that some of my farms virtual adaptors got created as
vlan adaptors (eth#.# instead of eth#:#) and if / when the cluster failed over
not all ip's failed over and I believe this may be the reason?
There is no need for these adaptors to be vlan they would be fine set as
virtual, I was wondering the best method to change them to virtual with the
least downtime possible as this is on a live system.
I'm assuming that it's probably rename the if_eth#.#_conf files to
if_eth#:#_conf and edit the file so the definition in the file uses : not . and
restart the zendloadbalancer service?

Hi Steve,
We've wrote a TIP in our facebook page to increase the throughput of ZenLB,
try this:
root ~# echo 100000 > /proc/sys/net/ipv4/tcp_max_tw_buckets
root ~# echo 5 > /proc/sys/net/ipv4/tcp_fin_timeout
Regards,
Laura.

We have the current release setup in a 2 machine cluster that runs an http /
https farms. We have setup our own farmguardian script and have had the farm
running for a long time with no problems in the test environment. We recently
went live and have noticed that the https farm averages around 500 Connections
which is fine and working however every once and a while the https farm just
stops on its own without warning and we have to restart it. This has just
started happening since we started to load it up. I have set the https farm to
a max connection limit of 30000 so this 500 connections shouldn't be causing
the issue however the farm is dying for no reason and it's becoming
concerning.. Any Ideas?
