With a larger amount of memory, a 32 bit system can get into really nasty situations, and in fact you can be OOM even if you have gigabytes of memory available! (just of the wrong kind). Using the -hugemem kernel helps some there (esp if you have 8Gb of ram or more), but fundamentally it's an unsolvable issue. Not that rhel3 does a good job at even trying, but still. -- Taroon-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/taroon-list
