Thanks Peter Stokes and Bill Voight. I had two suggestions to solve the problem: 1) Memory may be sensitive. Try another motherboard. 2) Reseat and switch the memory DIMMs over. If it persists it could be the motherboard. As I have tried various DIMMS in various machines and the problem occurs every few months. I have put new memory in two machines so I will do bit more testing and see what happens. If there are any more suggestions Please let me know. Regards Asif ------------------------------------------------------------------------------------------------------------------------------------------------------------- The Problem: Hello all 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 install 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...
