we are running Jboss 4.2.3 on Amazon AWS machine with 8 cores (CPUs) under load we see that there is a single thread taking massive load on just one CPU, while the other are almost idle. (other threads are distributed on all CPUs)
we see it using top.
we are using an AJP connector, connected to an httpd instance.
could it be the AJP connector thread? or anything else? some sort of threads manager thread?
any info will be appreciated.
