Hija,
I've just been able to again discover my memory problems, this time
under 2.4.26 as provided by the Debian people in compiled form:
kernel-image-2.4.26-1-k7
With kernel 2.4.23 and below the same machine worked just fine for
many months....
The net result is that I'm getting:
__alloc_pages: 0-order allocation failed (gfp=0x1f0/0)
__alloc_pages: 0-order allocation failed (gfp=0x1d2/0)
VM: killing process rsync
__alloc_pages: 0-order allocation failed (gfp=0xf0/0)
in my syslog messages.
Also ps shows that there's less than 100MB of memory in use by
processes but nevertheless a lot of memory is gone:
total used free shared buffers
cached
Mem: 515692 481756 33936 0 37772
64600
-/+ buffers/cache: 379384 136308
Swap: 262576 36360 226216
