HSVdatasource keeps growing

Hi,

I have a problem with the HSVdatasource.exe process continuously growing on HFM v11.1.2.0, I understand that assigning a value from 1-10 against statement cache in the windows registry settings should resolve the issue, however the client is presently using OLEDB 11.2 where it is not recommended to change the setting from the default of 0, would test this out myself but unfortuately there isn't a test or development environment. Has anyone experienced this issue (my own infrastructure experince is pretty limited)? 

Thanks
