This has been a major problem for us too. We had some CF apps that ran stable for months with 100's of users on CF 4.0 and as soon as we upgraded to CF 4.5 they would crash with only a couple of users. A 'Server busy' error would be displayed. After we locked all the writes to Application & session variables the apps were stable. Something was changed in the way CF handles shared variables between CF 4.0 & 4.5/5.0. Locking never seemed to be a major issue with 4.0 and now it is critical.

Palyne,
Unfortunately, yes. Lest you leave them alone and at the mercy of memory
corruption.
I know I have many applications where I haven't used CFLock at all.
However, all new development of mine is designed with locking scoped
variables - and as a result, I find myself less and less reliant upon the
session and application scope.
