Re: Normal CPU?

I think I need to rethink my question for you.

The original symptom that I was seeing was a SMTP process running at 
outrageous levels (80%+).  It was at the point that none of my users could 
connect (we are a one-system shop), so I took SMTP down and left it down 
for a while so they could catch up.  I left it down for quite a while, and 
Server started to go through the roof.  I turned SMTP back on and Server 
dropped down to what seems more reasonable levels, but SMTP ratcheted up 
to 95% after a while (sorry, not sure how long).  My WRKACTJOB just showed 
me 100.2% utilization -- now that's efficiency!  If only my users could 
connect...

A user contacted me to let me know that he's getting repeat copies of a 
message, and it seems to be each time I have to kill SMTP, he gets another 
copy.  There's nothing in mail.box for this message, but it has been 
delivered to his mailbox over twenty times.  The server has restarted (for 
backup) since this all started yesterday.  Any suggestions for where I can 
be looking to find and kill this ghost message?  Everything else seems to 
be related to this one message.  The secondary question, of course, would 
be what might make a message start doing this?

Patrick

PS  It looks like I was wrong.  I see PM400 on the system, but it doesn't 
appear to be started.

Re: Normal CPU?






I think so, but I will have to ask.  Am I correct in assuming I would have 

to order the software trial to proceed?  (As opposed to downloading an 
image from somewhere.)

Re: Normal CPU?






The 25ba is the i810-2467  The 2467 is a 1470 CPW system. 

The 522A is the i520 -8953 is the 2400 CPW system. 

(now you know how much growth you have)

So I would say if CPU popped after the upgrade we do have a problem.

Can you install PM400 and collect the data as I suggested?

Re: Normal CPU?






The 520 shows 9406 for the Main Card Enclosure (that's the number that 
looks familiar to me) and 522A for the System Processor Card

The 810 shows 9406 for the Main Card Enclosure, also, and 25BA-000 for the 



System Processor Card

Re: Normal CPU?






If you issue a go hardware option 4 
you will find something like this
 MP01             26F2       Operational           System Processor Card 

you can't view performance at a thread level without PM400, so a 
multithread job like server would be hard to debug.

PM400 ofters 30 day trials so you can use it to debug this without paying.

Re: Normal CPU?






Both systems are in another town.  Short of looking at the label on the 
front, how can I tell which models they are?  I'm relatively sure that it 
is a 520-9406, but haven't needed to know the 810's model for a while.

I don't believe I have PM400 on this system.  Should I?  Is there another 
way to see that information?

Thanks,
Patrick

Re: Normal CPU?






You don't say which 810 and which 520 but.

start with wrksysact  (you need pm400 for this).

It will provide a task list of processes consuming CPU.

Then issue set config debug_threadid=1 on the domino console.

match the thread from wrksysact using cpu to the console message with the 
same thread,


You now know WHAT is consuming CPU. 

Next, WHY?

that will depend on the what..

Normal CPU?






I have a new 520 (V5R3) -- online less than a week -- that is running the 
exact same load as the 810 (V5R2) that it replaced.  Same configuration, 
just saved and restored from server to server.  Something is bringing the 
new server completely to its knees (97%+ CPU utilization) and I'm not 
seeing what it is, so I'm wondering if anyone can provide ideas where I 
should be looking.  Originally, it appeared to be an SMTP issue and 
bouncing the SMTP task temporarily would resolve it, but I tried that a 
short time ago and never saw the CPU dip below 60% (the vast majority of 
it being the Server task).  We are a small shop and a third of my users 
aren't even on the server, so I can't imagine that we have legitimate 
traffic hitting me this hard when the old box would handle everything we 
threw at it without a problem.

Thanks in advance,
Patrick
