I noticed that my system is halting services for around 4-5 minutes, without sufficient logs on the system (system.log) that can bring me to the right conclusion (whether caused by unexpected reboots, etc). I then retrieved the system event logs (SEL) from the baseboard chip using FreeIPMI v0.6.3, and noticed for multiple "System Event #0:System Reconfigured" logs. The latest would be "54:23-Jan-2009 11:28:55:System Event #0:System Reconfigured" This is somewhat weird, as I did NOT change any in the system (BIOS, OS, BMC firmware, etc.) This is the cause of service halts as verified though my mrtg, and the system uptime. I usually get logs like the following (e.g. only) when such unresponsiveness is due to watchdog triggering, 24-Jan-2009 17:09:30:Watchdog 2 Watchdog:Hard Reset OEM defined = 00 00 00 00 00 E3 25 86 80 00 00 FF 00 or is simply due to manual/unexpected reboot ("init 0"/kernel panic): OEM defined = 00 00 00 00 00 E3 25 86 80 00 00 FF 00 With these, I suspect that the unresponsiveness of the system is not caused by a REAL reboots. Is there any possibily that the system's uptime can be changed even without restarting the box? What was that "system event #0;system reconfigured" mean? Is this related to SMM switching? by an attacker? Thanks, Won
