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.

wmmemload

WMMEMLOAD(1)						      General Commands Manual						      WMMEMLOAD(1)

NAME

       wmmemload - A dockapp to monitor memory/swap usages

SYNOPSIS

       wmmemload [options]

DESCRIPTION

       This manual page documents briefly the wmmemload command.

       WMMemLoad  is  a program to monitor memory/swap usages. It is a dockapp that is supported by X window managers such as Window Maker, After-
       Step, BlackBox, and Enlightenment.

       The current memory usage is displayed in the top half.  The swap usage is in the bottom half. It has an LCD look-alike user interface.  The
       back-light  may	be  turned on/off by clicking the mouse button over the appliacation. If the usage hits a certain threshold, an alarm-mode
       will alert you by turning on back-light.

OPTIONS

       This program follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is  included
       below.

       -d, --display <string>
	      Attempt to open a window on the named X display. In the absence of  this option, the  display  specified	by the DISPLAY environment
	      variable is used.

       -bl, --backlight
	      turn on back-light.

       -lc, --light-color <color>

       -h, --help

       -v, --version

       -w, --windowed

       -bw, --broken-wm
