[Spread-users] Invalid message in high load group

[Yuval Lifshitz]

I'm not sure the problem is in the daemon.
I use spread to send 100 bytes messages at 150 per sec
with the C interface (which is much thinner), and does
not encounter malformed messages. The problem might be
in the Java interface or maybe topology depended.
