Application caching Lucee 5

We have an old CMS that uses Application variable caching that appears to be suffering some of the other caching problems currently been dealt with in various Jira tickets. I’ve recently tried the 5.2.2.70-RC which appears to have addressed the issue we are having to some degree. I’m still having to re-start one of the application services to re-set the variables in some instances. I’ve not entirely pinpointed the problem as yet so I’m just interested to hear if this is a known problem or if anyone else is experiencing this kind of problem. I shall continue to investigate and try to provide more information once I know the root cause. The application question has just been migrated from Adobe CF9 to Lucee 5. Currently on 5.2.1.9
