Client process (uniengd) on the Calendar server is consuming 100% CPU usage

Question

The Calendar client bits in the Communicator 4.5 release (Calendar Build 981008)
are suspect of hanging the Calendar server when the end user uses the off-line
feature. The behavior seen will be that a cpu will start climbing and could
reach 80-100% of usage, which will cause the response time for all other end
users to be extremely slow and may not even accept any new logins.
<P>
The patch for these bits is available via the Smart Update (Windows and Mac) web
site:
<P>
http://home.netscape.com/smartupdate/su1_40.html
<P> Or you can download the complete version from
http://home.netscape.com/download/selectplatform_1_361.html
<P>
For Unix platforms, you will need to download the compressed tar file
(available from http://help/filelib.html#nscal)
and reinstall it.
<p>NOTE: To verify that you are executing a patched version, in the
Calendar client:
<b>Windows platform</b>
<br>Help menu pulldown, About Netscape Calendar, make sure it has <b>Build
981104</b> or higher.
<br><b>Mac platform</b>
<br>Select the file from your desktop
<br>File menu pulldown, Get Info. Make sure has a <b>date of 121698, version
4.51</b> or later.
<br><b>Unix platform</b>
<br>Help menu pulldown, About Netscape Calendar, make sure it has is <b>Version
4.51</b> or higher
<P>
The procedure for determining which user of Calendar is causing the server's cpu
hang is as follows:
<OL>
<LI>Using your favorite monitoring tool on the server, note the PID
     (process ID) of the uniengd process that is consuming
80 - 100% cpu activity.
<LI>Change directory to /users/unision/db/tmp/PID#
<LI>Execute the command "strings" on all the files in the directory
     (there are usually not very many):
<P>
          # strings *
<P>
     Near the end of the output, you will see the user's name.
<LI>You can now kill the uniengd process on the server:
<P>
          # kill PID# (note: do not use the kill -9 unless absolutely
          necessary!)
<P>
<LI>Contact the name of the user whose process you looked up and determine
     what version of Calendar client they are using. Immediately inform
     them of your procedure on upgrading to the correct version.
</OL>

Hi TrondWH,
Thanks for contacting Microsoft.
Currently, would you please try cleaning boot the server and test how the issue goes. Cleaning boot can exclude some third-party application affect. Following are the detailed steps about clean boot:
Log on to the computer by using an account that has administrator rights.
Click Start, type msconfig.exe in the Start Search box, and then press ENTER to start the
     System Configuration Utility.
On the General tab, click Selective Startup, and then click to clear the Load startup items check box. (The Use Original Boot.ini check box is unavailable.)
On the Services tab, click to select the Hide all Microsoft services check box, and then click Disable all.
Click OK, Choose Don’t show this message again and then click Restart.
Please check if the issue is still the same.
Please let me know the result.
Best regards,
Sophia Sun
