Subject: Odd size of Shared Memory
Date: Fri, 15 Jun 2001 10:34:50 +0200	[thread overview]
Message-ID: <20010615103450.A256@fourier.home.intranet> (raw)

I was trying 2.4.5-ac14 this morning. I issued some command to test
buffer and page cache behaviour

I run 2 cat /dev/hda > /dev/null and  find / -name \* concurrently

When find finished I ran free and it gave me

fourier:~# free
             total       used       free     shared    buffers	cached
Mem:        126996     124104       2892 4294967212      98944	9148

It seems a kernel bug to me, but it didn't hurt, my PC is working
without problems
