Canon EOS 10d & "Err99"
Discussion
So has anybody had any experience with this issue?
My 10d (bought the week they were released) is now showing this error every 50 or so shots, seems to be more often when using my Canon 300 zoom lense rather than my other lenses (but occurs with all). No real pattern but a power cycle cures - just annoys with time / shot lost.

Thanks! yup have seen this and tried it 
Looking for any other experiences as 'err 99' if the generic catch-all error message I agree with sideorb. I had this exact same error last year when I first bought my EOS 350D.
In my case the err99 error was caused by me using a Sigma lens which had an incompatible control chip. Essentially the error manifested itself whenever the camera tried to open the apeture fully and was getting the wrong return code from the lens.
In my case the fix was straightforward, as Sigma offer an inexpensive rechipping service (cost me £34 including postage & VAT). They cleaned the lens out & upgraded the control chip - job done.
On the basis of what you've written I'd consider getting the lens connections looked at if you're having the problem across a number of lenses. Probably a dirty/knackered lens contact.

Well @ Silverstone yesterday I got 'Err 99' about 40 times (managed to get 400+ photos though) - had freshly 'erased' both of the lenses and the camaera contacts that morning
The Camaera is a EOS10d and the lenses are Canon zoom EF 100-300 and Canon EF zoom 28-135IS - both worked perfectly for 3 years until about 6 months ago.
The 'err 99' comues up more often with the 100-300 lens but does occur with both. Sometimes when is occurs the view through the view finder is 'darker' (as if shutter half open/closed)until the next half press of the button...
Any thoughts or any recommendations for service / repair? or should I look at new kit?

Is there "play" where camera meets lens?
If you look through the viewfinder and half press the shutter release button the aperture and shutter speed should be displayed...if you wiggle the lens about and the illuminated information disappears/reappears, then you definitely have excess wear at the bayonet mount. Firing the camera when the info is not lit (proper contact) you will get the Err 99 code.

sadly no play - now trying to decide how to progress. Does anybody have any recommendations re Canon service locations? So far I've managed to locate the following but haven't heard much about any of them...

Last year while covering most of the WRC events and the BTCC I started having E99 lockups all the time on my 20d, you could turn it off and back on and the error would still be there, so I became a dab hand at doing a speedy drop off of the battery grip and back on again at which point the error would 75% of the time be gone, but when you would then take another snap the pic would be extremely dark and often would throw the error up again, so I would throw the button down and run off maybe 10 snaps at which point the light would have returned to normal and no error apparent.
This got very annoying after a month or so as always seems to be the case when you need the camera to work it would always foul up resulting you missing a car in mid air or the likes...
I took the bull by the horns at home and set the camera up on the tripod and ran it through several hundred snaps with 4 different lenses, and I found that the error would almost always be caused by my 70-300 Canon tele lens...I did the usual search google for help etc, and ended up venturing into my toolbox from the main job to get a PCB eraser and cleaned up the contacts on the lens (I was going to do the camera body too but the fact of shedding particles and CCD stopped me from doing so).
The lens then worked with only a few minor stalls over the next 3 months or so until I upgraded some of my kit (one of which was a new 300mm tele lens) and since then I've never had a single E99 error on either my 20d or 400d bodies, so I'm putting the error down to the lens in my case at least, but I would agree that the E99 error definitely seems to be the "emmm not sure so we'll just call it one of these" error codes...
