Dear misc@, I'm having problems with my HP ProLiant DL140 box running 5.3. About once every week or two the machine crashes to ddb with the following message:
> uvm_fault(0xfffffe807711e1d8, 0x7fbfbffffe38, 0, 1) -> e > kernel: page fault trap, code=0 > Stopped at pmap_enter+0x145: movq 0(%rdx,%rax,8),%rax > ddb{0}> The system is completely unresponsive then, making it impossible to do anything with ddb on it. I found a similar thread here: http://openbsd.7691.n7.nabble.com/uvm-fault-crash-on-fresh-4-2-td52785.html and the conclusion there is that the ram is faulty. I've run memtest a couple of times with no errors detected and `stress` spinning a couple malloc()/free() threads for a couple of hours with the system running with no results. Is there any other possibility for the uvm_fault except bad ram? If not, can you think of any way to reproduce the problem in a reasonable amount of time to find the faulty ram chip? Thanks in advance ;-) Dmesg attached below: OpenBSD 5.3 (GENERIC.MP) #62: Tue Mar 12 18:21:20 MDT 2013 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 2145452032
