Hi team, The 'default-jgroups-tcp.xml" has MFC protocol without the FRAG2/3 protocol. This is broken when we send a multicast message larger than 'max-credits'. It will block forever in MFC [1]. No timeouts since we don't have the CompletableFuture at this point.
Possible solutions are: #1 put back FRAG2/3 advantage: we have multicast flow control. disadvantage: all messages are fragmented (unicast and multicast), that probably requires more resources (more messages in NAKACK and UNICAST tables?) #2 remove MFC advantage: probably low resources usages. TCP will handle any fragmentation. disadvantage: we don't have multicast flow control. #3 alternative? Cheers, Pedro [1] actually, I need a thread dump to confirm it. _______________________________________________ infinispan-dev mailing list infinispan-dev@lists.jboss.org https://lists.jboss.org/mailman/listinfo/infinispan-dev
