Agreed, increasing the timeouts is probably not the way to
go. However I am at the mercy of whatever Infinispan is doing. As
for the notion of Infinispan being tested at 1000 nodes:<br>

and I'll have to wait until I get home to dig up an email that I think I
have.<br>
<br>
However, I'm not assigning blame, I was under the impression that it had been
tested at 1000 nodes. I just had it up at 430 nodes, but I can't reliably get
it to that size when I restart it. I think the answer is that Infinispan will
have to use what will scale in JGroups (remove what does not scale). Until then
I will have to scale it down to a size that I can start in a reliable fashion.<span

Still no answer on whether ISPN-83 will be in 4.2.1.....</span></font></p>

style='font-size:10.0pt;font-family:Tahoma'>Specifically, Infinispan throws a
config exception if FLUSH is *not* present. However, we did cut a release
without this check and ran our defaults without FLUSH. It worked well
enough for most people, except one important use case. And this is what needs
further investigation. It seems as though the problem with that use case
was not the removal of FLUSH, but some dependence in the test in question on
FLUSH. But it's too late in the 4.2.1 cycle to pull something like
this, hence my proposal to leave FLUSH in by default but to allow a
FLUSH-free config via a (temporary, 4.2.x only) system property while we
investigate properly removing FLUSH in 5.0.</span></font></p>
