Very Computer

I have been testing and trying to find the problem for some hours now.
System boots fine, but there appears to be a problem with memory/buffer
cache management. After a few minutes to half an hour, the machine
seems to page constantly. I was re-compiling the kernel while running X,
and after a few minutes response to mouse movement slowed, and eventually
stopped. Disk activity gets very intense.

Testing with a freshly booted kernel, I found that paging was occuring
when not expected. ("ls" in one window, focus to another window, focus
back, "ls" and wait while shell pages back into memory). The response
degraded gradually at first, then more rapidly. All this time the
amount of disk activity was rising exponentially.

Sorry I have nothing more to go on yet :-(

                                                cheers

        What? Didn't you guys hear? This was a lot of hard work by
Howlin' Bob. He has given dosemu (...the DOS emulator) the heavily
demanded "look and *feel*" of DOS/Windoze.

Sorry - couldn't resist that one. On a more serious note, have you
applied the malloc patch that H.J. Lu posted to the sources of 4.4.1 ?
It's just a stab in the dark, but....

Regards,
Paul.

No X here, kernel compiled with gcc 2.4.5, libc 4.4.1. No ethernet cards
installed, but networking code compiled into the kernel, and loopback
seems to work. Oh, this is a noname i386/33, w i387/33. Nothing fancy.
