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..
