Description simra 1999-05-28 14:37:49 EDT
Here's my system: i686, 128MB RAM, 136548k swap space.
kernel 2.2.5-15,  passing kernel flag "mem=128M".

When my swap space is exhausted, the machine simply stops.
It's not thrashing- it just stops.  No mouse response, no
keyboard response, the HD LED is not on.

It's very difficult to collect any other diagnostics, but I
was watching 'top' as the machine ran out of memory and top
observed that the swap space remaining was 0k.

I will forward this bug report to
linux-kernel@vger.rutgers.edu

I should mention that I'm using the stock kernel from the redhat
distro. The following modules were resident:

Module                  Size  Used by
nfs                    29944   9  (autoclean)
lockd                  30856   1  (autoclean) [nfs]
sunrpc                 52356   1  (autoclean) [nfs lockd]
3c59x                  18920   1  (autoclean)

The "solution" is to add more swap space. There are many, many
deadlock conditions in the kernel that can be exercised by running
out of swap.
