Patrick Hunt updated ZOOKEEPER-336:
-----------------------------------

    Assignee: Henry Robinson
      Status: Patch Available  (was: Open)

Hi Henry, from your comments it looks like you're ready for review, in 
ZooKeeper (hadoop in general) this is indicated
by clicking "submit patch" on the left hand side of the JIRA page. This 
triggers the review/commit workflow - in 
particular it will run the hadoop qa bot and let us (committers) know to review 
for commit. The process is
documented here:
http://wiki.apache.org/hadoop/ZooKeeper/HowToContribute

It's also fine to submit drafts and ask for review, but I think in this case 
you are saying it's ready for final review (correct
me if I"m wrong). One nice thing about submitting is that it's listed on the 
project page as "patch available" and ensures
that we won't overlook it.

I will review this presently.

> One user saw a case where a single mis-programmed client was overloading the 
> server with connections - the client was creating a huge number of sessions 
> to the server. This caused all of the fds on the  server to become used.
> Seems like we should have some way of limiting (configurable override) the 
> maximum number of sessions from a single client (say 10 by default?) Also we 
> should output warnings when this limit is exceeded (or attempt to exceed).
