Publishing a map Service taking over a day in 10.1, only took a few minutes in 10!

Discussion created by RachelB on Dec 8, 2012
Is it normal for when Publishing a Map Service, the 'Creating Service Definition' part takes over a day in 10.1. The folder size says 50mb but it's still running for 24hrs and the size hasn't changed.
I published the same mxd in 10 and it used to take a few minutes.
I do have quite a few layers in there but why such a big difference between the 2 versions.
Or has mine just got 'stuck' and I should cancel it and start again?
