This KB article may help explain it. KB12912 I cannot say we saw a significant improvement when we turned it on, however we did not do any real analysis. We did notice that the CPU utilization did drop a little (but noticeable) on our SA-6000's. There have been many issues with the Cavium chip set, so you need to confirm with JTAC whether you can turn it on with your Code version.

This issue took months and months for JTAC to figure out. The issue is within the Index.dat file and affects IE 6, 7 and 8. We are a large company that is still using IE6 so we were not able to confirm the issue in IE7 and IE8. Clearing out the temp internet files in IE7 and IE8 should fix the issue...but only temporarily (according to JTAC). In IE6 it requires a 3rd party tool. Of course, until you upgrade to 6.5R4, it is possible and in many cases very likely to return. We reimaged PC's and rebuild user profiles only to have the same issue return after a day in some cases, a week or 2 in others and in a few cases never. The fix did not make the cut off date to be included in the latest 6.4 update so right now it is only included in the 6.5R4 code. Thanks, Tim

The issue is finally fixed in 6.5R4. cachecleaner-end-user - Cache Cleaner is causing the CPU usage on the user's PC to increase to 95-99%. (470734) Here's the basic issue. The problem is in clearing the history file of the IE. The code is written with an assumption that a URL entry cannot be more than 512 bytes. But with latest fixes in IE 6.0 browser, the URL can be more than the expected length. The implementation of considering 2 bytes to get the URL length from the index.dat (the history binary file, that can?t be edited by user) has now been changed to consider 4 bytes to get the URL length so the fix is with the Cache Cleaner exe not the system.

I'm still waiting for a solution from Juniper. We have learned that rebuilding the user profile does resolve the issue.

We have seen a few users who have issues with dscachecleaner taking up 50% of the CPU cycles on the pc. What we have noticed is that dscachecleaner starts even when the user is not using the SSL VPN. This situation is occuring for a handful of users out of over 10,000 users. We are running version 6.3R3 and in the process of upgrading to 6.3R4. I have a case open with JTAC but right now we are stumped as to what is causing the issue. Our users are running Windows XP sp2 and sp3. We have done the basics of removing all the Juniper Components, removing the directories, removing Reg entries. That takes care of the issue until the next time the user connects to the SSL VPN. We are having the users end the process manually as this does slow down MS Outlook and MS communicator. Has anyone else seen this? Thanks, Tim
