This seems to have slightly improved the situation, now my tail test program finishes, but a buildworld is still too much for the machine. It prints a page fault in kernel mode message, with the following details: fault virtual address 0xfffff037 instruction pointer 0x8:0xfffff037 stack pointer 0x10:0xc8346318 frame pointer 0x10:0xc8346e8c code base 0x0 limit 0xffff type 0x11 DPL 0 pres 1 def32 1 gran 1 before it prints a DDB prompt, there is another page fault, which is identical apart from: instruction pointer 0x8:0xc0262fe8 stack pointer 0x10:0xc8346c84 frame pointer 0x10:0xc8346c88 then I get a DDB prompt. Asking for a stack trace just produces another page fault. David. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
