Hi Eric
shutdownGracefully(seconds);
Thread.sleep(2000);
startup();
it consistently works. So this is a timing issue. The MBean-Method
shutdownGracefully returns, before the server sockets are closed. The
strange thing is, that I was not able to reproduce this issue in other
environments. Maybe this is because the machines in this environment are
much faster. The whole cluster-reload takes less than a second without
the sleep.
Could you please check the code for a bug! We need this feature to work
reliably.
I went through the code, and I do not see any issues,.. however, can you
check the following on your different systems:
$ cat /proc/sys/net/ipv4/tcp_tw_reuse
$ cat /proc/sys/net/ipv4/tcp_tw_recycle
Those define how soon sockets can be reused, and I think this could be
OS specific. Even for the ESB shutdown, I included a 3 second delay just
to be safe, and I think something like what you discovered would be the
best option
