Chances are there was no problem. The kernel uses any memory that applications, etc, aren't using for caching files, etc. It leaves a small percentage of memory unused so when new processes start there's memory available for them. If the unused memory gets a bit low it shrinks the cache a bit. And if a few processes exit and the unused memory gets a bit large, it lets the cache grow a bit. There's been a few discussions here before, you might like to have a look at the archives for more details. There's some analysis of the output of the "free" command, for instance. -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
