Hi,
I'm running an embedded tomcat, so I don't have the server.xml file.
When I place a breakpoint in the selector loop though I find that the
value of selectorTimeout is 1000.
Regards,
Sebastiaan

Subject: NIOSelector busy wait
Hi,
I have a problem that sometimes the NIO selector goes into a busy
wait loop.
In line 1430 the code of NIOEndpoint.java,
keyCount = selector.select(selectorTimeout);
select keeps returning 0 without waiting.
I'm running on the latest trunk version of tomcat 6, on Ubuntu Linux
Feisty, with java version:
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) Server VM (build 1.6.0-b105, mixed mode)
However, I've seen this same behavior with other JDK's (1.5).
To me it seems that it's a bug in the JVM implementation because
select should only return 0 if it's woken up, which does not happen
(since all other threads are suspended in my debugger). However, I
was wondering if anybody else has seen this behavior and perhaps
knows what's causing it in the first place.
Regards,
Sebastiaan
