Hello Experts,

I have a Windows 2000 member server that is using up to 99% resources due to a process called lmgrd.exe.  I've searched around the Internet and found that this might be related to my Matlab install.  We are using and older version (Version 6.1.0.450,  Release 12) and can no longer get support from Mathworks (the makers of Matlab).  The software is installed and used on the server for license distribution.  When clients open Matlab on their workstations, the license server checks to see if a all 6 licenses are in use.  If not, it lets the person use the software.

Although the CPU usagae on the server is up to 99%, clients can still connect and open Matlab.

I'd like to bring this CPU usage back down to normal if possible.  I've checked the event logs and found nothing that relates to Matlab.

Please help!

Thank you.

Hello mb2010!

Your in luck!  I am the License Server Manager for my employer!  I ran into this too and yes, lmgrd.exe is your FlexLM licesne server running the FlexLM server service.  First, stop and restart the service.  If no joy, then you'll need to backup the license.dat.  Remove all instances of FlexLM including the service.  Re-install FlexLM then the license.dat.

If still not joy, although MathLAB has gone out of business, you should still be able to get vendopr support for the software IF you company purchased a support agreement.  If not, then you're out of luck.  I make a big deal about support agreements with my employer and they keep everything updated and paid for for me!  Are you that MathLAB wasn't bought out by another company?

Check http://www.mathworks.com/cgi-bin/texis/webinator/search/?db=MSS&prox=page&rorder=750&rprox=750&rdfreq=500&rwfreq=500&rlead=250&sufs=0&order=r&is_summary_on=1&ResultCount=10&query=FlexLM&submitButtonName=Search

Andre,

Thanks so much!!!!

I had to backup the license.dat file, remove all instances of FlexLM including the service, and then Re-install FlexLM, then the license.dat.  I could not have done it without that URL you provided.  That's a wealth of information.

Oh, and if you'd like another 20 points, just go tohttp://www.experts-exchange.com/Operating_Systems/Win2000/Q_21888278.html and enter the URL for this page.

Thanks again!

I've deleted the other pointer question.  Not sure if that was right to keep it up.  Thanks again for your help.
