I suspect you are starting the postmaster under resource constraints
(check "ulimit" settings) or else the postmaster is getting hit by the
kernel's infamous "out-of-memory killer" (google for "OOM kill" for more
info).
In recent Linux kernels you can prevent OOM kills by adjusting the
kernel's memory allocation parameters, but RH 7.2 may be too old to give
you that control.
