Are you able to try some of the following settings (mentioned earlier
in the thread):

vm.min_free_kbytes = 16384
vm.overcommit_memory = 2
vm.overcommit_ratio = 75
vm.lower_zone_protection = 100
vm.vfs_cache_pressure = 10000

In addition, you can always tweak with the /proc/<pid>/oom_(adj|score)
files in RHEL5 and make VMware impervious to the OOM killer.
