To follow up from David, the amount of 'leakage' is also variable from run to run. If it was just plain fragmentation I would expect the memory usage to be at least consistent. We are also seeing that some objects are being allocated without a GC descriptor. I noted Zoltan's response about the GC_GCJ_MALLOC functions and need to read the code again. We also have a theory that with libgc the false pointers on the stack aren't being removed from the mark stack when the execution stack unwinds. I will be investigating this. - Dick _______________________________________________ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list
