[Bug 55692] Re: Kernal 2.6.15-26 Server Memory Leaks and Disk I/O errors

[Ben Collins]

I don't see anything out of the ordinary. You have a lot of cache used,
but again, that's normal, especially if you are doing a lot of disk
related things (like web, sql, etc).

The cache isn't "used memory" per se, but it does show up in the free
list as being used. If userspace programs need this memory, the kernel
will automatically free from the cache.

I think the memory aspect of this bug report is a non-issue. If you want
more assistance with the I/O error, please provide a full dmesg with
this problem occuring in it.
