Hi Couple of thoughts to proceed:
1. Boot with kmdb attached on system console (serial/local). When this happens, F1-A into the debugger and do some looking around. When you're at it, also take a crash dump/stacktrace for others to take a peek. Here's the guide: http://docs.sun.com/app/docs/doc/816-5041/chp-kmdb?a=view 2. Run iostat, prstat at very high priority on a local/serial console. Better not use it over network and don't pipe it to file. If IO is blocking somewhere, it'd take them down too! Better not block on anything but locally attached/serial console! 3. Use DTrace toolkit and dtrace the hell out of the system, preferably using dtrace enabled mysql from coolstack. 4. Upgrade from snv_40, the debugging has pretty good chance of turning up something that might have been fixed many moons ago.
