ePO 4.0.0, NAC 3.1.0: CPU 100% at all time


Does anyone use the ePO, and have the problem about CPU utilization 100% at all time?

My server is running with the ePO 4.0.0, and NAC 3.1.0. Its CPU utilization is about 100% all time. The processes those consume most of the CPU are tomcat5.exe, Apache.exe, EventP****r.exe, Mcshield.exe The tomcat5.exe process usually consumes most of the CPU utilization, greater than 50% most of the time. I can login to the ePO console with very slow response from the server. And sometimes I couldn't login to the ePO console.

Does anyone know why these processes have consumed most of all the CPU Utilization?
And what are they used for?

Does anyone deploy NAC and has a kind of this problem?
This problem seems to happen after deploying NAC.
We firstly deployed just only the VSE8.5, and had not see this problem.
But after deploying NAC 3.1.0 for a while, the ePO server's CPU utilization is about 100% all the time. When we deployed just a small portion of NAC clients, the problem didn't occur.

Are there any limit of the number of NAC clients?

Please suggest,
Thank you.

Hi, try the following:

HI,try this...please feedback and let me know if this solves the 100% problem related to mcshield.exe


Repeat: Problem found, work around below.

Problem: McShield.exe consumes 100% of CPU for long periods of time (>1 hour).

Work around:
  a. Invoke McAfee Security Center to feed McShield a "cookie" aka cookie monster. (This work around is less than optimal as it degrades over time.)

b. Search for McAfee anti-spam file error logs, (there are four of them). When found, delete the error logs in these files.( Over time, repeat as necessary.)

C:\Documents and Settings\All Users\Application Data\McAfee\MCLOGS

Comments: On inspection the logs are "forever logs" that accumulate reports on all errors  encountered by the various McAfee modules. Four modules have log files, these log files appear to "carry over" when an upgrade or a relicense is performed. Inspection of the dates on the logged errors show dates from the first installation up to the current run time. Note that the three machines I have examined all have the same symptoms of 100% CPU consumption and all three cleared up when the files in question were eliminated. The files appear to be diagnostic in nature and would be used by programmers to determine what failed, when it failed and in what module it failed for the McAfee modules.

It appears that McShield processes these logs on every system startup and on every system return from standby. This effect is what causes the consumption of 100% of CPU for extended periods.

A suggestion for a rapid work around would be a simple program that downloads to the user computer, targets these files and moves or deletes them from the error logging that is being processed by McShield.exe.
Note that the Customer Service does not understand this problem and denies it exists.

Intake Tier wanted to re-install McAfee.
Tier 2 claims my machines are virus impaired and wanted me to visit the McAfee Virus Removal team.
Tier 1 wants to educate me on how viruses get onto machines.

Everything recommened by Customer Service avoids addressing the McShield.exe problem...actions just work to cover it up. This is a systemic McAfee Organizational problem reflected in the inablilty to admit a problem and fix same.


delete the contents of the McAfee "error log" files
