Hi,
I have a computer that freezes a few times each day and dmesg shows manyof the
following messages:
Jan 26 17:18:01 adalind savecore: [ID 570001 auth.error] reboot after panic:
anon_decref: slot count 0
I have no idea what is the problem although I suspect that somethingis wrong
with the hardware. Can anybody enlighten me a bit?
Regards,
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..).
