Darrel Schneider created GEODE-9367:
---------------------------------------
Summary: support cache server max-threads on Windows with ipv6
Key: GEODE-9367
URL: https://issues.apache.org/jira/browse/GEODE-9367
Project: Geode
Issue Type: Improvement
Components: client/server
Reporter: Darrel Schneider
The cache-server has a feature called max-threads that allows a large number of
client connections to use a smaller thread pool. Instead of every client
connection owning its own server thread, multiple connections can share the
same thread.
However if the server is running on the Windows operating system using ipv6
this feature is not supported.
The code that causes this is in AcceptorImpl line 479:
{code:java}
if (tmp_maxThreads > 0 && isWindows) {
// bug #40472 and JDK bug 6230761 - NIO can't be used with IPv6 on
Windows
if (getBindAddress() instanceof Inet6Address) {
logger.warn(
"Ignoring max-threads setting and using zero instead due to
JRockit NIO bugs. See GemFire bug #40198");
tmp_maxThreads = 0;
}
{code}
Note that the warning text is wrong but the comment about the jdk bug is
correct.
But according to this page:
[https://bugs.java.com/bugdatabase/view_bug.do?bug_id=6230761]
the jdk bug was fixed in jdk6u33 on 2012-07-30 so I think this restriction
should be removed since geode no longer supports the old jdks this bug was in.
