The machine has 4GB of RAM and initially I set it up with vm.kmem_size and vm.kmem_size_max set to 1024M. It's my home fileserver and I'm the only regular user. After booting the box I had tested the transfer speed back and forth over the net and after that not really used it any more that day. The next day I discovered that it had crashed sometime during the night. I've since changed the two tuneables above to 1536M and I've not had any crashes since. I also tried with 2048M but that only resulted in a crash upon boot. Kind regards Morten StrårupReceived on Sun Jan 06 2008 - 20:33:18 UTC
