Bakunin,

I concur too. I am not sure what is causing these errors and they seem to last for a couple of minutes and then they would not appear for the rest of the day. Then they would not occur for a couple of days and then they would prop up. Seems very strange. We do have java processes that are event driven by MQ. In fact our MQ itself has a java wrapper around it. Since I am not a root user I will post everything except svmon -G output.
Here are the rest of the outputs that you

As soon as I can get one of the UNIX admins to work with me on the svmon -G command I will post the results of that command as well. Thank you for your comments.

NAME

       update-java-alternatives - update alternatives for jre/sdk installations

SYNOPSIS

       update-java-alternatives [--jre] [--plugin] [-t|--test|-v|--verbose]
	     -l|--list [<jname>]
	     -s|--set <jname>
	     -a|--auto
	     -h|-?|--help

DESCRIPTION

       update-java-alternatives  updates  all alternatives belonging to one runtime or development kit for the Java language.  A package does pro-
       vide these information of it's alternatives in /usr/lib/jvm/.<jname>.jinfo.

OPTIONS

       -l|--list [<jname>]
	      List all installed packages (or just <jname>) providing information to set a bunch of java alternatives. Verbose output  shows  each
	      alternative provided by the packages.

       -a|--auto
	      Switch all alternatives of registered jre/sdk installations to automatic mode.

       -s|--set <jname>
	      Set all alternatives of the registered jre/sdk installation to the program path provided by the <jname> installation.

       --jre  Limit the actions to alternatives belong to a runtime environment, not a development kit.

       --jre-headless
	      Limit the actions to alternatives belong to the headless part of a runtime environment.

       --plugin
	      Limit the actions to alternatives providing browser plugins.

       -h|--help
	      Display a help message.

       -t|--test
	      Don't  actually do anything, just say what would be done.  The implementation status of this option is the same as for update-alter-
	      natives (not implemented).

       -v|--verbose
	      Verbose output.

FILES

       /usr/lib/jvm/.*.jinfo
	      A text file describing a jre/sdk installation. Consists of some variables of the form <var>=<value> and a list  of  alternatives	of
	      the form jre|jdk <name> <path>.
