We have recently recieved a 3/280 running SunOS 3.5. Currrently there are 10 diskless 3/60 clients and 2 3/60 standalones on standard eithernet. Otherwise the net is empty. All entries to the net are Muxed ( except the 3/280). Our problem is random panics (3/280) with a condition of 'bad rmfree'. Virtually everything on the 3/280 has been replaced, including the backplane. The kernel is generic and has been rebuilt from other 3/280's in house. Sun's suggestions have been to replace the memory boards, cpu, increase swap space to 50M and run a generic kernel. All of which we have done to no avail. Subsequently we have replaced just about everything. Our only non-Sun element of the system is Aviv 450/451 controller adaptors. Which have also been swapped out (with more Aviv's). We have also tried eliminating all clients. Occasionaly we have lost /usr. Mounted ro to all clients. When we rebuild /usr and regenerate our kernel the system usually stays up and error free for 30 - 36 hrs. Otherwise we are lucky to stay up for 2 hrs. Any help would be greatly appreciated.
