LMS3.2 GUI unexeptable slow / Tomcat need 98% CPU

Unanswered Question
Dec 8th, 2009

Hallo,

We have problems with a new installed LMS, with a very^(very^(very^(very^(very))))) slow GUI. We rebooted the system the 3rd time now and the problem still appears.

Reason could be the tomcat, wich pulls 96-100% CPU permanent.What can we do, to can work with the LMS-system?

Plattform:

Win2003r2 Standard,SP1, EnUS, 4GB RAM, Pagefile = 2 times physical, VM

Steffen

I have this problem too.

I had exactly the same problem and never actually got to the bottom of it..

After 3 months of trying and many WebEx sessions with Cisco TAC we gave up and rebuilt the server from scratch.

On advice from Cisco TAC when we re-built the server we put HUM and IPM onto a different server but configured Single Sign-on with one serve configured as the CS master.

Everything is working fine now and the performance of both servers is excellent..

I just wish I knew what solved the problem, the re-build, splitting the modules across 2 different servers or a combination of both!!

For the record out initial server was exactly the same spec as yours and CiscoWorks was managing around 350 devices..

Hello,

Thx for your quick response.

@Jo: there is no response to this Site

http://SERVER:1741/cwhp/ThreadDump.jsp

HTTP Status 404 - /ThreadDump.jsp

type Status report

message /ThreadDump.jsp

description The requested resource (/ThreadDump.jsp) is not available.
Apache Tomcat/5.5.17

http://SERVER/cwhp/ThreadDump.jsp (Cut&paste from you)

http://SERVER/cwhp/ThreadDump.jsp (Cut&Paste from LMS)

Firefox kann keine Verbindung zu dem Server unter a.b.c.d aufbauen.

same with IE

---------------

We did a platform upgrade to can use 2 physical CPU from the ESX server for the LMS-VM-Guest.

After changing system HAL to apply the CPU's, we got :

You don't have permission to access /cwportal/c/portal/login on this server.

After LMS-Login

So we did a complete Deinstallation and a new Installation

@Developers: The uninstall takes more than 2 hours! Most time consuming is psu for RME,CV,DFM during uninstall!

Now its working again, but still slow and still heigh Tomcat load (less than before, because the 2nd CPU)

further investigation:

- SW: no IIS, .Net Framework 1.1, OpsXML (http://openxmldeveloper.org/default.aspx, is this comming with LMS or can we deinstall this)

- Services: Daemon-Manager can start Tomcat only, other services has to be startet manualy (same behaviour than before platform upgrade)

@Blue8

HUM is not installed, IPM is installed but with no inventory/Collectors yet.

It really sounds like you have a bad installation.  The ThreadDump.jsp page should exist if you have LMS 3.2.  Additionally, all daemons should get started by Daemon Manager.  I would highly recommend you contact TAC so they can provide you the clean_system.exe utility, then walk you through the recommended steps to ensure a good Windows installation.  You should not be seeing the problems you are seeing.

It is a LMS3.1 in real. The order for that installation was called LMS3.2 for this customer. I realized that one day after, sorry.

I would still open a TAC service request to analyze this problem.  There is still a way to capture a thread dump of Tomcat to see what it's doing.  It's a lot more complex to do in 3.1, but it is doable.  I still think that you have a bad installation, but it would be beneficial to get remote access to take a deeper look at your server.
