There are some known issues with running start twice. I thought it had been fixed in 4.7. But if you have a system crash, you should submit a stack back trace. If you have a page fault, don't worry. Several per second are quite acceptable: r b w avm fre flt re pi po fr sr s0 m0 in sy cs us sy id 1 0 0 27704 2636 262 0 3 2 5 8 26 0 131 4294966892 48 34 11 55 1 0 0 28784 1552 276 0 0 0 0 0 3 0 108 577 17 78 22 0 1 0 0 29908 832 284 0 0 0 0 0 0 0 104 388 17 85 15 0 See the column 'flt'? That's the number of page faults per second on this machine. It's high, but not serious.
