Thanks Peter Stokes: Peter suggested to replace the motherboard.
This problem is occurring on number of machines and it happens randomly after every few months. Is there any other fix
i.e. Any tester program that test the memory and the motherboard. I used the SIMCHECK II PLUS memory tester to test the memory but it passes all the
memory.
I am running SunOS 4.1.3_U1 on Sun Sparc 5s. Time to time I get the Async Memory fault ; Panic on CPU 0 and machine reboots.
I have installed the jumbo patch 101508-15 and 101592-09 and replaced the memory SIMMS number of times in various machines
but I am still getting the fault.
Initially I use to get Watchdog error and I installed the patch 101508-15 and 101592-09 for that and since than I never had a watchdog reset.
But async memory fault is still a big problem.
Can some one get me out this jigsaw. Many thanks:
The early messages for Async memory fault:
vmunix: Async memory fault mfsr=0x81802860 mfar=0xbb75598
vmunix: panic on cpu 0: async memory fault
vmunix: syncing file systems... VAC ENABLED
.....

and machine reboots
