memory errors on a P6

I reported an earlier oops on several Gateway P6-200's we have running
RedHat 4.2, kernel 2.0.30. These have 64M RAM, 128 MB swap, DEC Tulip
-SMC8432 cards.

Now, I can confirm that in each case the problem appears with the
message:

free(8060008) above top of memory.memtop = 8070800 membot = 8063f18

Exactly the same message on each of three machines.

I am doing rlogins on each. After the message appears, I can do one or
two commands, there is a Seg Fault, and then the rlogin closes.

The machines have been up for 21 days or so. On one of the machines the
message log shows the following.

Couldn't get a free page.....
Couldn't get a free page.....
Couldn't get a free page.....

It looks like this is a memory problem. I doubt that all three machines
would have bad memory. This may be a problem in how the memory is
accessed.

Anyone else seen the problem?
