The kernel-hugemem is a 32-bit-only kernel. When RHEL 4 was released (around February 2005), 64-bit systems we not that ubiquitous. It still made sense to use a 32-bit OS with the typical 8 GB servers. The context has changed now, and Red Hat no longer support more than 16 GB on 32-bit platforms as of RHEL 5. The output from Alt+SysRq+m should always fit in a kernel log buffer. Try collecting that one to be certain that the issue is related to VM management. However, I'd seriously suggest moving to RHEL 4 for x86_64 as you should still be able to run your 32-bit application, minus a whole class of VM hassles. -Imed -- Imed Chihi - ØÙØØ ØÙØÙØÙ http://perso.hexabyte.tn/ichihi/ -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
