I'm trying to restrict GHC to 800Mb of heap at runtime by passing in +RTS -M800M, the machine has 1Gb of memory and top shows free physical memory dropping below 175Mb.
-M800m should do more or less the right thing, but it is possible for GHC to exceed this figure by a small percentage.
Is there any chance there is a bug in recent GHCs (or perhaps Linux?) affecting this? I'm fairly sure I've lately seen Haskell programs consuming significantly larger amounts of memory than they should be allowed to, and I can try to isolate a test case if it is of interest. -k -- If I haven't seen further, it is by standing in the footprints of giants
