[OpenIndiana-discuss] Machines freezes...

[Apostolos Syropoulos]

Yesterday I managed to upgrade the system. I will use it today and if nothing will happen, then probably there 
was something wrog with the OS. Otherwise, the hardware is definitely faulty.

anon_decref() is called in a number of places in the virtual memory 
system when it is releasing a reference to an anonymous page (a page 
that isn't part of a named filesystem object).

These pages are reference counted (as they may be shared between 
processes due to a fork()); panic("anon_decref: slot count 0") is called 
when the page being dereferenced already has a reference count of zero.

This could be due to memory corruption due to bad memory or a 
misbehaving CPU, or it could be a software bug, but I'd expect to see a 
range of panics if it's a hardware problem.

Getting more of the panic stack trace would possibly be informative (it 
could help narrow down the context and possible contributing factors..).
