2.4.27 suddenly hangs

Hello, all!
Iâm not sure that the below problem is kernel related, however, I think, this mailing list is the best place to start. I've got 2x1.8 Xeon on Intel SE7500CW2 motherboard with Intel SCSI RAID (GDT driver). The system powered by Red Hat Linux 7.3 with custom kernel version 2.4.27.
Occasionally, the system just hangs, without giving any error messages to syslog or any panic-like messages to the screen. No response to ping. Usually it happens on weekends in early hours, but not at particular time and day, when usersâ activity is minimal. Couple of times the last few messages before, the hang had strange timestamps. It seems like the system time entered a TIME LOOP within a period of 1 second.
Nov 6 05:37:31 service dhcpd: Message...
Nov 6 05:37:32 service named: Message...
Nov 6 05:37:31 service named: Message...
Almost all the time last messages came from different services, except three times, when mgetty was the last. I'd updated mgetty, pppd, kernel (from 2.4.20), BIOS, dhcpd etc., however, the problem remains.
Can anyone tell me, how I can detect, what application or hardware cause such a problem.
Any ideas would be appreciated.
Thank you in advance
