In Process Explorer we have 7 CCLWriteDump.exe processes that are (currently) 4 days old. They are what we call orphans, they are not in a process tree/not sub-processes of a "main" process. Does anyone know what these are? I can't find anything on the web. I think they are hung dump file processes and should be ok to kill the process, but I want to be sure.
any input is greatly appreciated.

I suspect these processes are initiated when your BI server processes crash unexpectedly. The idea is that the memory the server process was using gets written out to a core dump file on disk, which can then be interrogated by IBM support to help them understand what caused the BI server process to crash unexpectedly. I think CCLWriteDump.exe is the process Cognos uses to create these core dump files. If you look in the bin64 folder of your Cognos install, are you seeing any core dump files? The are usually named core.<date, time and some other numbers here>.dmp and they can be quite large.
I'd say it's ok to kill these processes if they are hanging around and not finishing. It's worth doing some digging to understand what's causing the core dumps in the first place, though.
