Description Ondrej Nevelik 2012-09-10 09:22:56 EDT
During multiplecaches test in Library mode (i.e. there are ~50 caches running at each node) this IOException appears: 
ERROR [org.jgroups.protocols.UDP] (DiagnosticsHandler,x,edg-perf01-39764) failed sending diag rsp to /
java.io.IOException: Message too long
	at java.net.PlainDatagramSocketImpl.send(Native Method)

For the server log, either see the stdout.zip or have a look into the loganalasis/slave folder.

Nothing really to see here: JGroups diag is broken and it should never be enabled in the configuration (it is disabled in default server and library configs)
