    server startup hang/high cpu on Solaris 9

    jason barlow Newbie

      Have a third party application running on app on Solaris 9 , jboss 3.03, tomcat-4.1.12

      The jboss run.sh script intermittently appears to hang. What happens is one of the lwp hogs a load of CPU.
      All in USR accoring to prstat.

      PID USERNAME USR SYS TRP TFL DFL LCK SLP LAT VCX ICX SCL SIG PROCESS/LWPID
      27268 siebicm 98 1.6 0.0 0.0 0.0 0.0 0.1 0.0 2 24 641 0 java/17

      Took some threaddumps and the corresponding thread (nid=0x11 matches LWPID=17 in decimal) is in java.util.HashMap.get called from org.jboss.mx.loading.UnifiedLoaderRepository2.loadClassFromCache
      (full stack below)

      Have increased logging is the last message is :

      2006-04-25 14:58:13,971 DEBUG [org.jboss.system.ServiceCreator] About to create bean:XXX
      2006-04-25 14:58:13,971 DEBUG [org.jboss.system.ServiceCreator] code: xxx

      The actual bean can name can vary which makes it more annoying.

      I cannot find anything on on this so grateful of any ideas..additional troubleshooting that could be done to get bottom
      of this.

      thanks harry

        • 1. Re: server startup hang/high cpu on Solaris 9
          Scott Stark Master

          This is a ridiculously old release of jboss. The UnifiedLoaderRepository2 codebase is obsolete due to bugs.

          • 2. Re: server startup hang/high cpu on Solaris 9
            jason barlow Newbie

            Thanks for the response. We have analyzed a little more on the log files from hanging issue and find out the hanging issue is always after the thread dump.

            Here is the jboss infrastructure from the failing scenario:

            There are 3 jboss nodes (node1, node2, and node3). node1 and node2 sit on solaris box1. node3 sits on solaris box2. node1 is JMS provider and node2 and node3 are JMS listeners with MDBs. The protocal between JMS client and server is RMI.

            At node startup time, node2 and node3 will shake hands with node1. The hanging happens 1 out of 10 and always happens on node3. It seems to be some combination issue of Solaris/Network/Distributed JBoss/JMS issue.

            Here is the full output of the thread dump. Could you please check it out and let us know if it rings any bell of some bug related to this issue?

            Thanks a lot,
