would so appreciate help.
a process called rapimgr.exe takes up %100 of my cpu. A quick internet check
reveals that this process is associated with activesync. Sure enough when, in
desperation, i uninstalled activesync the problem went away. As soon as i
reinstalled it, it came back. This happens continously regardless of whether
or not my Ipaq is connected. It severely slows down my laptop and often
causes windows to crash altogether. I don't know what to do. I have a feeling
this may have something to do with my McAfee software though i have set it to
always allow anything even remotely related to this product. Does anyone have
a suggestion? A quick internet search found numerous users with this problem
but no solutions.

Did you notice that you told us *nothing* about your system?  Not what type
of device it is, what version of the OS is on the PC, what type of PC, how
you connect to the PC for ActiveSync, etc.

The process is always running on a PC that has ActiveSync on it, but it
should only be using CPU cycles when the device is connected, in most cases.
The only exception I can think of is if you have installed some after-market
application which does some operation with the mobile device external to
what ActiveSync does itself.  It might be a program that automatically
copies one or more files to or from the device, etc.  If you're absolutely
sure that this is not the case, then my best guess is that you have
connected a cable to the PC from a device type that makes AS think that your
mobile device is connected.  What port connections have you enabled in the
Options for AS?  Serial port, maybe?  Something plugged into that serial
port?

I'm having the same problem (AS is using 49% CPU in task manager, which
translates to 100% cpu of one of the cores in the X2). Here's some details:
- Outlook 2003 SP1
- Never had AS installed on this system before (new computer reload)
- AS version 4.2
- ipaq hx4700 with windows mobile 2003 SE ver 4.21.1088 build 15045.2.6.0
- Computer is a AMD X2 4400+ custom built with 4gb ram (3gb identified
in windows) so it's a dual processor. DFI CFX3200-DR MB for USB, with
ATI x1900 video card.
- cable for computer connection is USB. Serial is disabled in AS config.

There is no other third party software that does firewall (just MS one
with XP SP2 which is turned off BTW), or even Antivirus.

There is no software in the desktop config of AS. The pocketpc has apps
installed, but those were from my old computer and so just reside on the
pocketpc now. They were installed with AS 3.8 never had a problem (there
was no rapimgr.exe with AS 3.8)

Any further ideas? Need any other info, feel free to ask :)

This happens when the device is *not* connected, correct?  I can't explain
it.  You could try disconnecting all USB peripherals from the computer, I
suppose.

sorry about the lack of details. i dont really know enough about these things
to know what info would be relevant. i have an ipaq and a dell inspiron. i
should add that a) i have no software that didnt come with the ipaq b)i never
used to have this problem and c) i am using a laptop and absolutely nothing
is connected to it.

It happens after a reboot with no PDA connected.

Unplugging all the USB devices doesn't make sense to me, as the USB bus
should keep each of the devices independant.

I'm wondering if it's a problem with the AMD X2, and multi-processor.
Maybe the manager is unable to allocate the resources correctly to a
single CPU, and goes into a loop trying to do so?

I'm willing to work with any of the MS devs on this to narrow the
problem down, but otherwise I'll just have to downgrade to AS 3.8.

Thanks,
David Troesch

There's about zero chance that you'll find any actual dev. guys joining this
particular thread.  You can call MS for support, pay the money, and you
might eventually get some help, but that's the only way that you can be
relatively sure of getting the problem in front of the dev. team.

Please actually try the USB thing.

If you are up for it, you can also try the steps at
http://BevHoward.com/ASync.htm#RAPI but they are far from perfect.

fwiw, I gave up and went back to 2003se

Among other things, windows media player on the desktop relaunches
activesync and rapimger and I found that since I used wmp, I was
contstantly having to execute my killwcescomm batch file to regain
reasonable use of my computer... got to the point where when it dawned
that things were slow, I would run it without even looking to see if
async had restarted.

I was basically doing that manually already (don't have to end
wcescomm.exe because that doesn't spike CPU usage) :)

As a FYI I don't even notice the performance decrease with the AMD X2,
I'm really liking this system. I've had several things that started
looping, and I've never felt the slowdown (just upgraded from a P4
1.6GHz and there's a BIG difference :) The processor seems to have so
much raw power with it's multi-processing that anything that starts to
have problems just happens on the one core and the other core keeps the
system peppy.

I forgot about that, I do have Media player 11 Beta for XP, I wonder if
it's the problem. I wonder if anyone is having the problem with Media
player 10.

I think I'll probably just downgrade to AS 3.8 and go from there. Less
headache :) Thanks Beverly

Hmm. I am having the same problem with rapimgr.exe using 100% CPU. I have a
2.6Ghz single core laptop w/ 1.5 GB RAM WinXP Home SP2 and ActivSync 4.2.0
(Build 4876).

rapimgr.exe runs on startup whether I have any USB plugged in or not. I
haven't sync'd for about a dozen reboots either (nobody probably cares about
that one).  But I DO have WMP11 Beta!  It sounds like this isn't the culprit
however because I'd guess that Noni isn't running WMP11 Beta given that
he/she has an apparently stock Dell Inspiron.

Each time I reboot, I stop the rapimgr.exe process with the Windows Task
Manager and haven't had any problems yet. In fact, just in the process of
getting my ActivSync version for this post, I had to start ActivSync... and I
look in Windows Task Manager now only to find rapimgr.exe using 0% CPU and
5,788 K Mem Usage! so you're on good behavior now, are ya?

So the temporary fix seems to be to kill the process but surely there must
be something better.

I had the same problem and I noticed it after I upgraded to Windows Media Player Version 11 (11.0.5721.5145).  However, I also remembered blocking connection to the internet when configuring the firewall (because I didn't know why activesync needed to connect to the internet and still don't know why), so I put it on the list of "allowed" programs that could connect to the internet.  I think rebooted and the problem went away.  Rapimgr.exe still runs but it takes very little from the cpu now.  That's my experience.  Good luck!
