Late summary because this one has taken a bit of time to resolve - we had to wait for the machine to crash before we could make any progress. Thanks to: Adriaan Kotze Henrik L. Poulsen Michael Kiernan mike.salehi@kodak.com Jeff Horwitz Greg Gallagher Michael suggested adding snoop=1 to the kernel, and do a sync from the openboot prompt the next time the system crashes. This will create a dump that we can then send off to Sun. snooping=1 is also known as the deadman timer according to the Sun support guy I spoke to afterwards. Jeff suggested booting with the kernel debugger using 'boot kadb' from the openboot prompt. Both good suggestions. I have added the kernel parameter, but .. unfortunately? .. the system hasn't crashed once in the last two weeks. I'm having this idea that it's related to Solstice X25 and the SunSAI/P ports on the box, but I cannot prove anything as long as the machine hasn't crashed. Original question: We have a problem where an e250 (Solaris 8) hangs so bad that not even the stop-a key combination works. No coredumps are generated, the entire system is frozen and we can't do anything but flick the power-key. SunVTS and Openboot diagnostics don't find any errors. I'm looking for ways to reproduce this to try and figure out where the cause is. Does anyone know of various ways I can try and get an e250 to hang? I know it's not network related, so flood ping and all that stuff is no good. I have got root access and physical access to the box.
