Fw: [Spread-users] Connection reset using Java API

[John Lister]

Cheers for the reply. any questions are good as i'm just beginning my
 experience with spread :)

I have 2 machines on the same subnet, one sends messages and the other
receives (consumes) them.
So it looks like you are right, i didn't realise that i had to consume my
own messages on the same daemon
while blindly following the examples which join the group.


As the sender doesn't need the message am i better not joining the group or
setting SELF_DISCARD in terms of performance?

Cheers, I would never have thought it was a buffer problem as the number of
messages seems to be slightly variable, but the time frame between resets is
almost exact.
