tweaking srun

While trying to figure out a problem that may or may not be with resin 
(I may be back with this one in a day or two).  I discovered some 
unusal behavior while trying to tweak the srun configuration.

I'm trying to tweak resin-3.0.6 for a high traffic, very short response 
website.  I wanted to adjust the 'timeout', 'live-time' and 'dead-time' 
properties of srun, from the config docs:

http://caucho.com/resin-3.0/config/resin.xtp#srun

None of these properties seem to be valid.  When i set one, resin tells 
me:

conf/resin.conf:67: `live-time' is an unknown property of 
`com.caucho.server.cluster.ClusterPort'.

So i go an remove the - character to see if it a spelling mistake, but 
resin just tells me this:

conf/resin.conf:67: live-time="5s" is an unexpected attribute in <srun>.
<srun> syntax: ( (@id | @server-id | <server-id>)?
               & (@backup | <backup>)?
               & (@dead-time | <dead-time>)?
               & (@host | <host>)?
               & (@index | <index>)?
               & (@live-time | <live-time>)?
               & (<openssl> | <jsse-ssl>)?
               & (@port | <port>)
               & (@protocol | <protocol>)?
               & (@tcp-no-delay | <tcp-no-delay>)?
               & (@timeout | <tcp-no-delay>)?)

'backup', 'dead-time', 'live-time', 'protocol', 'tcp-no-delay' or 
'timeout' are expected.



Are these indeed the right property names and place to be modifying 
them?  I only did a quick search through the archives, and bug lists 
and could not find anything related...so hopefully I'm not repeating a 
question that's already been answered some where else.
