We have been running a LVS cluster for many years using the WLC
scheduler which works fantastically well.
Thank you everyone involved in the project.
However we now have a requirement to also run a cluster using the
Source Hashing scheduler, which is
giving us a few problems.
We would like to limit the number of connections to a real server and
it seems this should be possible
by setting the weight at a appropriate level.
The snippet below seems to indicate that there may be a bug in that the
number of active connections
for each of the real servers below is well beyond the expected 800.
That or I've misunderstood

My questions being has anyone else seen/experienced this issue and if
so how did you work round/fix it?
