Some RAM checks wouldn't be out of place either.
Memtest86+ has now been running for 20+ hours and no errors has been found. I was also unable to reproduce this problem, but it only happened after a few days of constant activity anyway so I guess it's not so easy to replicate. Any other pointers where to look at? Your help is well appreciated.
