high cpu utilization due to java

Hi,

my Ciscoworks LMS 2.5 was experiencing high CPU load. Everytime i open the CW application CPU instantly increases to around 90%.

Hope you can help me resolve this issue.

Below are the data from the server:

Re: high cpu utilization due to java

Can you also get the output of the pdshow command at the same time this is occuring? Then you can match the PID from above with a PID in pdshow to see which LMS process specifically is causing this problem.
