[jboss-cluster-dev] Conversion from FD to FD_ALL

[Brian Stansberry]

I have a task to convert JBoss AS's UDP-based stacks from FD to 
FD_ALL.[1] I want to make sure I understand the configuration correctly 
such that I can get the same behavior as we have now for the simple case 
where one node crashes. (I realize FD_ALL can detect multiple failures 
more quickly, which is good.)

The AS currently uses:

<FD timeout="6000" max_tries="5" shun="true"/>

Would this be fairly similar:

<FD_ALL timeout="30000" interval="6000" shun="true"/>

In both case it takes 30 secs to suspect a node, in both cases a message 
is sent every 6 seconds, and in both cases 5 such messages would have to 
be lost for some reason before a healthy node would be suspected.
