Default svchost 100% CPU and Possible windows update problems

Vista Basic Machine started running very slowly and when I looked in Task
Manager svchost.exe was using a 100% CPU. Using system internals process
explorer it’s the network service containing crytsvc, dnscach, KtmRm, NlaSvc,
Tapisrv and Termservice.

Looking inside the thread that is using the CPU is ntdll.dll

I’ve ran all virus and spyware checkers I can and all show no problems. I’ve
booted in safe mode and cleared all the softwaredistribution folder. The slow
running does not affect safe mode but as the service is not started no great
surprise. Windows Update doesn't work in safe mode either, thanks Microsoft.

I tried to update AVG virus checker but it wanted KB929547 applied so I
downloaded it and tried to run but after several hours all I got was install
failed with 0x800706bb

Any ideas??

Default svchost 100% CPU and Possible windows update problems

For what it's worth, I had the same problem about a month ago. It was
svchost.exe that was spiking the CPU. Did some trial and error with
services and couldn't nail it down. It lasted about 2 weeks
(intermittently) and has now not reared its ugly head for a couple of
weeks now.

I think I read somewhere that it was a conflict with the virus app? I'm
using eTrust. Not sure, but possibly an update fixed it? Good luck!

Default svchost 100% CPU and Possible windows update problems

I just swapped from AVG7.5 to 8.0 and problem is still there However making
some progress as if I look at the Process explorer properties for svchost the
thread it reports is ntdll.dll!RtlUserThreadStart and suspending this makes
the machine usable. So I’ve been trying various things to no effect to help
the problem.

The AVG8 scan finds nothing.

Currently uninstalling Windows Live xxxx as there are reports, all be it old
ones, that this can cause problems and I’m also in the process of getting the
flashplayer update as this was also mentioned.

However even with the CPU down very low (with thread suspended) the Windows
Installer crawls along, well uninstalling in this case.
I’ll keep looking and report back on findings.

Thanks for posting the link....haven't had the time to do an in depth

information will come in real handy.... :-)

Default svchost 100% CPU and Possible windows update problems

Thanks for the suggestions no solution yet but more information.

The sysinternals process explorer has shown it’s a single thread causing the
problem and it’s identified as ntdll.dll!RtlUserThreadStart Killing this
thread fixes the problem but it returns on a reboot or possibly restart of
the service(s) I’ve only tried cryptsvc so far but that causes the problem to
reoccur.

Tried the Kernrate as suggested and it is showing ntkrnlpa with fltmgr
second but the first it 80% the second was 4%.

Looking at the stack information from process explorer I see top of the list
ntkrnlpa.exe!KiUnexpectedInterrupt+0x40

Also I’ve updated all the drivers on the system and anything else I can
think of with no effect.

Default svchost 100% CPU and Possible windows update problems

I'm running Windows Server 2008 AD on my laptop that I use an an Instructors server in the classroom. I've left it on for a couple of days, and this morning, all 4GBs of RAM were used and my CPUs were sitting on 100%.  I brought up Process Explorer and checked. Under a scvhost.exe, there were over 600 taskeng.exe jobs scheduled.  I open up the object, and there are two ntdll.dll!RtlUserThreadStart threads.  I tried to get the laptop to reboot, but apparently my RAM crashed into the virtual memory and went BSOD.When I reboot, there are not tasks scheduled.   After a few hours, there are a couple of dozen. Then there is more and more.  It's been about 12 hours since I rebooted, and I have about 130 taskeng.exe jobs pending.Any Ideas?

Follow up to the problem.

The only way of fixing it was to do a total re-install of Vista. Once that
was done and all the updates applied and applications re-installed the
machine runs without problems.

Obviously there was some sort of corruption somewhere but there was no
malware detected anywhere on the system. The only two items that may be
related was there were some dodgy MP3 played which may have automatically
downloaded a codec containing malware. Also the system was reporting traced
of having Norton installed and to my knowledge it had never been near the
system.

It's typical for a virus to inject itself into a svchost process. I would do a full scan/reinstall.
