  • Linux Jetty Java EE High Load Problems

    Java EE, Linux Ubuntu Server, Jetty
    Linux 2.6.32-22-server #33-Ubuntu SMP UTC 2010 x86_64 GNU/Linux

    For some reason the JSVC process is at almost 300% (I think the max is 400%. It's a dual core with hyper-threading.)
    PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
    22639 jetty 20 0 1509m 426m 13m S 295 11.0 778:00.27 jsvc

    I don't like having it that high. There's definately something wrong. The uptime also indicate high load (app. 20 when it should be at 4)

    root# uptime
    14:10:23 up 100 days, 19:51, 4 users, load average: 22.75, 22.46, 22.31

    I'm not too experienced with these things. I've tried reducing the hibernate-spring.properties
    +++++++++++++++++++++++++++
    -hibernate.c3p0.initialPoolSize=10
    -hibernate.c3p0.maxPoolSize=25

    persistence.xml
    +++++++++++++++
    -<property name="hibernate.connection.pool_size" value="20" />
    Prevoiusly they were much higher.
    Merely starting Jetty sends the jsvc-process to 300%.

    How do I get down the load to a reasonable level?
