***Update*** April CU contains the fix - http://blogs.msdn.com/brismith/archive/2009/05/01/project-server-2007-check-in-pending-laid-to-rest.aspx Thanks for all your help!
Thank you all for your continued feedback saying we still haven’t nailed this – and the offers of copies of caches and repro steps. Fortunately we had an internal Microsoft user who read my blog and offered his repro and cache which gave us the benefit of a local repro where we could get at both his cache and his server (Thanks Ken!).
The result of this is a better understanding of where we need to look to resolve this issue and also, with all your feedback, confirmation that even deleting the cache folder (which is now accepted as the best quick fix – as long as your project is REALLY saved and checked in on the server) does not mean the problem will not come back. The problem would appear to be some sort of corruption in the cache that can be re-introduced from a suspect project. Aik now has the smoking gun, and the issue is making its way into our hotfix process (See EPMConnect for other on-demand and Live webcasts).
good to hear that you guys are engaged to solve the most annoying problem of the project server environment! :)
Greetz from Germany,
What's the ETA on the hotfix for this?
Always difficult to give ETA's for fixes in the pipeline - but we usually target the next available CU - which in terms of our process will be April (too late for the upcoming "February" CU) - but a risk to promise it will get in this early...
do you have an update on this, we're getting fairly late in April and the SP2 is out - after VERY initial testing with SP2 I am still seeing this issue - so I would like to know whether the target is still the April CU?
I'll do a full post hopefully tomorrow, and yes, this is still due to be shipping in the April CU. It is not addressed in the SP2 just shipped.
