Sorry, forgot to mention that we are getting the oom-killer with another
application, we are not using VMware.
The total low memory reported by the PAE and the normal kernel are the same
PAE
# free -lm
total used free shared buffers cached
Mem: 7994 348 7646 0 70 179
Low: 827 102 724
High: 7167 245 6922
-/+ buffers/cache: 98 7896
Swap: 4094 0 4094
#
Normal
# free -lm
total used free shared buffers cached
Mem: 3930 309 3621 0 17 196
Low: 859 47 811
High: 3071 261 2810
-/+ buffers/cache: 95 3835
Swap: 4094 0 4094

Both commands were executed just after a reboot of the system and it's
interesting to see that the used low memory in the PAE kernel is the double
of the used low memory in a "normal" kernel
We already tried the parameters that Ray suggested and they didnt make any
difference.
vm.lower_zone_protection is not available in the rhel5, so we are going to
try with less memory and see what it happens.
Thanks all for the information/suggestions, this thread has been excellent.
cheers,
C.
