Dear Rainer,

if no one else is experiencing these errors, then it is probably a
hardware error.
I had once encountered problems with incompatible memory (combination
of memory (ok with other boards) and board (ok with other memory) did
not work properly). The issue could be triggered with a simple
buildworld within minutes. However memtest86 could run for hours
without finding a thing.
Please don‘t rely on memtest86 if it does not report any problems.

To be sure: check / adjust memory timings, remove and/or replace
memory modules and try to trigger the error again.

Best regards,
Holger Kipp



I have this problem on two machines, actually.
It would be highly unlikely for both to have hardware problems.
Though possible, of course.

Reducing ARC seems to help, though, and I assume that is the problem the machine ran into because I still have 29GB out of 32GB wired now, with an ARC limited to 60% of kmem_size.
