@yogeshkore, @mathias , @steevebisson,
Uncontrollable grow of GSI is a known problem for 4.1.X branch. 4.5.X allows to use circular logging (and many more improvements in GSI implementation), that solves the problem. I can suppose that 2 sequential manual compactions probably could help, but that is nothing more then a suggestion
