I've been seeing this effect since 4.3-RELEASE actually. WIth pretty much identical symptoms to the ones you descibe. Asking here earlier people seemed to think that it was the disc controllers getting locked up as this will lead to the effects described. Sometimes the machine will run for weeks at a time, sometimes it will freeze after a few hours. The easiest way I can make it lockup is to try and access a very large file from two processes at once. I'm currently trying to find time to work out how to use the kernel debugging stuff to connect over the network and see what sort of state the kernels in (which it is apparently posssible to do). But not really got anywhere with that yet. I'd be intyerested in knowing what sort of machine you have and what the components are to see if theres anything that both systems have in common (other than the SMP bits). cheers, -pcf.
