statistics need to be enabled.
for messaging add <statistics-enabled>true</statistics-enabled> to messaging subsystem under <hornetq-server>
and in ejb3 subsystem add <statistics enabled="true" />
It appears that nearly all Runnable threads hang in a system code
at sun/nio/ch/PollsetArrayWrapper.pollsetPoll(Native Method)
These threads are actually not application default-threads, but "default I/O" threads.
What are these threads for? Can the number of I/O threads be reduced? Is it meaningful?
Can you upgrade wildfly to 8.2 and what is the JDK you are using? any chance you can upgrade to latest 7 release?
The version is AIX specific
java version "1.7.0"
Java(TM) SE Runtime Environment (build pap3270sr6-20131015_01(SR6))
IBM J9 VM (build 2.6, JRE 1.7.0 AIX ppc-32 20131013_170512 (JIT enabled, AOT enabled)
J9VM - R26_Java726_SR6_20131013_1510_B170512
JIT - r11.b05_20131003_47443
GC - R26_Java726_SR6_20131013_1510_B170512
J9CL - 20131013_170512)
JCL - 20131011_01 based on Oracle 7u45-b18
I requested an upgrade of java but it will take some time. We'll get the latest pap3270sr8fp10-20141219_01, 220.127.116.11, SR8 FP10 in March probably.
Same for wildfly.
It might be an AIX issue
yeah I think it also might be JDK on AIX issue. or AIX itself.
It is hard to tell as we don't have any AIX to test on
