Huh, I've hit this independently sometime in the early spring and since
then I have a comment about that in our configs :) But this is certainly
not the issue now.

Hi Radim,
If you're using VMs, this may be of use. I actually
experienced a JGroups
lockup in production with FC in decrementCredits. What
happened in my case
is that virtualization tools had actually screwed with the
system clock --
it was reported that JBoss took ~1 year to start.

The upshot is that I had to take FC out of my stack going forward.

Subject: [infinispan-dev] Is anyone else experiencing JGRP-1675
Hi,
since Infinispan moved to JGroups 3.4, we're experiencing
occassional
deadlocks in some tests - most of threads that send anything
over JGroups
are waiting in JGroups' FlowControl.decrementCredits. The
problem sometimes
goes away after several seconds, but it produces some ugly
spikes in our
througput/response time charts. Originally this affected just
some RadarGun
tests but this is appearing in some client-server tests as
well (we've
recently investigated an issue where this appeared in a
regular soak test).
I was looking into that [1] for some time but haven't really
figured out the
cause. The workaround is to set up MFC and UFC credits high
enough (I use
10M) and stuff works then. I was trying to reproduce that on
pure JGroups,
but unsuccessfully.
I am not asking anyone to dig into that, but I wanted to know
whether QA is
alone experiencing that or if there are more of us.
