[javagroups-users] UDP not working in AIX

[Robina B. <rob...@gm...>]

Hello,

We are using JGroups to establish communication among nodes in a cluster.

We are using the following protocol stack,

"UDP(mcast_addr= 228.8.8.8;mcast_port=45566;ip_ttl=32;"
            + "mcast_send_buf_size=64000;mcast_recv_buf_size=64000):"
            +
            // "PIGGYBACK(max_wait_time=100;max_size=32000):" +
            "PING(timeout=2000;num_initial_members=3):"
            + "MERGE2(min_interval=5000;max_interval=10000):" + "FD_SOCK:"
            + "VERIFY_SUSPECT(timeout=1500):"
            + "pbcast.NAKACK(max_xmit_size=8096;gc_lag=50;retransmit_timeout=600,1200,2400,4800):"

            + "UNICAST(timeout=600,1200,2400,4800):"
            + "pbcast.STABLE(desired_avg_gossip=20000):"
            + "FRAG(frag_size=8096;down_thread=false;up_thread=false):"
            +
            // "CAUSAL:" +
            "pbcast.GMS(join_timeout=5000;join_retry_timeout=2000;"
            + "shun=false;print_local_addr=true):"
            + " pbcast.STATE_TRANSFER(down_thread=false;up_thread=false)";

and it works fine with windows and solaris. But its gives the following
error in the AIX operating system.

Stacktrace of the error in AIX,

Could anyone please help us in getting rid of this error in creating
sockets?

Does JGroups works fine in AIX? Is it problem in using UDP? Should we switch
to TCP?
