Welcome!
The situation is this:
There are 2 servers, each one spinning on JBoss'at 4.2. Each JBoss'e revolves on the app (let them be A and B). Annex a goes to B on the EJB. Everything works as it should.
However, there is a problem:
The first JBoss'and gradually increasing the run time GC for young generation. Shortly after this time is 0.1 seconds, and in three days already 1.1 seconds. Thereby increasing the load on the server and decreases the application throughput.
About the settings:
Use -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:NewSize=1024M -XX:MaxNewSize=1024M
While JBoss'e Appendix B all is well.
There is a suspicion that this increase is caused by the fact that A is connected to B, because a similar situation was repeated on the other JBoss'Oh and apps.
Tell me, please, what can grow these pauses?
