Hi Jeremy, the problem is that none of the user mode processes (even Xorg) show any significant memory usage, even after 3//4 days - but the total memory used shown in top is huge and system acts very sluggish. Which leads me to think its probably the kernel memory being leaked. Some has indicated that its the way Linux VMM handles memory (even though top shows huge amount of memory is being used, its just that "page tables are cached") - but in that case why does the system becomes sluggish if the purpose of caching is to increase performance? It would help to know how many pages are being used by what process in the kernel memory space but I am not an expert to investigate this, perhaps there is a utility I can load as a kernel module which writes the logs to a file..
