I've been poking around the system I'm running and sniffing for anything unusual.  I'm not sure how many "Red Hat Enterprise Linux ES release 3 (Taroon Update 4)" systems are in production with NetView but it's not yet approaching the majority from what I'm seeing on the mailing list. 

I've tried to keep things somewhat clean but there are a number of items I've found where a little feedback would comfort me. 

·       I have about 100 Java processes running when I do a "ps -ef | grep java".  Is this as expected?
o       Many date back to this morning when I would expect the web consoles to be logging on.  These are with names of maptreeserver and virtualdesktop as I would also expect

o       Another group of many threads are listed as: /usr/OV/jre/bin/exe/java -Xmx64m -Djavax.xml.transform.TransformerFactory=org.apache.xalan.processor.TransformerFactoryImpl -Dnetview.home=/usr/OV -Djetty.home=/usr/OV/www -Djetty.log=/usr/OV/www/logs -cp /usr/OV/www/classes:/usr/OV/www/lib/ibmjsse.jar:/usr/OV/www/lib/jav.  There are batches of these in groups of one to seven.  Most show start times at various times for today and others dating as far back as the last time I did an OVSTOP/OVSTART sequence a week ago. Are we littering the environment or are these older ones expected and functional?

o       Most of these threads have something like 00:00:01 processor time attributed but there are a few exceptions.  
·       During the past week (or since the last total restart of the NetView security and postmaster) I've accumulated the following processor times.  Except for where I've had no background they make sense. I can't judge the "l2_event_adapter" on the first line and the "Transformer" ones on the fifth and ninth lines.  Can anyone reassure me they're normal?  OVSPMD has been running since June 2 when I did a total restart (nvKill).     

o       1010m   0 l2_event_adapter -i ../conf/l2_event_adapter.ini -c 1
o       685:28   0 /usr/OV/bin/ovspmd
o       122:40   0 poll_server -i ../conf/poll_server.ini
o       74:55   1 /usr/OV/bin/ovtopmd -O -t
o       48:57   0 /usr/OV/jre/bin/exe/java -Xmx64m -Djavax.xml.transform.TransformerFac
o       47:32   1 /usr/OV/bin/ovwdb -O -n50000 -t
o       30:58   0 /usr/OV/bin/netmon -P -I -S -s/usr/OV/conf/netmon.seed -u -h -K1
o       26:21   0 l2_topo_adapter -i ../conf/l2_topo_adapter.ini
o       24:20   0 /usr/OV/jre/bin/exe/java -Xmx64m -Djavax.xml.transform.TransformerFac
o       23:11   1 correlator -i ../conf/correlator.ini
·       With all the Java threads I mentioned above with low processor times and the two high processor Java threads in the second area in stark contrast, am I missing something that's out of kilter? 

I plan to restart the daemons this evening (OVSTOP/OVSTART) --- just in case.

Reassurance and comments are invited.
