We recently loaded an IBM X366 4processor box with RedHat 3.0 update 5 x86_64 64bit. We now see occasionally over night or throughout the day system hangs. To the point where the interfaces may be pingable but ssh or telnet are not allowed. Connectivity through a RSA-II card is allowed but the remote control capability is useless. At this point only a system reset clears up the system so it can be accessed once again. Diagnosis from the RSA has been run and comes back clean. No error logs explaining loss of power or temp warnings. No loss of network connectivity or cpu/memory failures. The system simply locks up. Any help would be greatly appreciated. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Scott K.
