It's probably not the kernel per-se, but the filesystem's buffer cache. Run "free" and look in the "cached" column. The fs buffer cache will use as much memory as you have. You will still hit swap occasionally, but generally, buffers should be purged from the cache to allow other processes access to physical memory when needed. David -- [EMAIL PROTECTED] mailing list
