We, regularly, had a CPU usage issue and the server CPU got to 100% for the Orchard project issue.
Using thread profiling we find that NHibernate was responsible for it.

With further investigation we find this helpful link:

and this fix:
https://github.com/nhibernate/nhibernate-core/commit/c0c981825294f90997980cd26d0774be29da298e

Now, by upgrading NHibernate.dll form 3.3.1.4000 to 4.0.3.4000 our problem has been fixed and since then the rest of functionality and modules are working properly.

Any comments?

We have already migrated to 4.0.1 in 1.x branch, which contains the fix. We might want to upgrade to 4.0.3 if necessary.
