400 - Session Timed Out - Please log in again

Hi all,

Since upgrading to PPM 5 SP10 we have been experiencing some timeouts on Item creation. When creating an Item from the Initiative and after clicking the 'save' button, an error is thrown:

Data is saved, i.e. the Item is still getting created, but this is confusing/disturbance to the user to see this message

Any ideas?

Thanks

C
