#11116: GC reports memory in use way below the actual -------------------------------------+------------------------------------- Reporter: | Owner: facundo.dominguez | Type: bug | Status: closed Priority: normal | Milestone: Component: Runtime System | Version: 7.10.2 Resolution: invalid | Keywords: Operating System: Linux | Architecture: x86_64 Type of failure: Runtime | (amd64) performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonmar): Also note that the RTS only tracks memory that is allocated on the Haskell heap, it doesn't track memory allocated by C libraries, `malloc`, or `mmap`. So there are several reasons why the memory figure reported by `peakMegabytesAllocated` might be less than the RSS figure from the OS. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11116#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
