Hello,
It started again and was on thread 3187 (see tomcatdump-8.0.24-2015-08-02.txt)

java.lang.Thread.State: RUNNABLE
at org.apache.tomcat.jni.Poll.poll(Native Method)
at org.apache.tomcat.util.net.AprEndpoint$Poller.run(AprEndpoint.java:1810)
at java.lang.Thread.run(Thread.java:745)
I managed to get the debugger attached and a breakpoint in AprEndpoint class
line 1802 (below), it seemed to be going in a loop which was consuming the
cpu.
// Poll for the specified interval
for (int i = 0; i < pollers.length; i++) {
..
}
the variable pollers.length == 1
For some reason it stopped breaking and the CPU went back to normal, after I
held it on the breakpoint for some time as I was looking at the source, so not
sure?
Cheers Greg
