These all seem completely normal, your RAM is fine. >'Disk Cache Misses' as high as 126 K File was read from the hard disk, since it was not already present in the cache. It is common for files to be read from hard disk. >'Memory Manager Discards' up to approx. 600 Information in memory was discarded, presumably because it was no longer needed or unused or somesuch. >'Memory Manager Page Faults' spiking up as high as 5.6 K Memory page was retrieved from virtual memory (hard disk) where it had been placed after a period of non-use.
