Two sizes of benchmark were used, which use either a 45Mb or 102Mb array. The first panic occurs with either the 45Mb or 102Mb array, I've only seen the second with the 45Mb array. swap_pager: out of swap space panic: rlist_free: free start overlaps already freed area at list tail Debugger("panic") Stopped at Debugger+0x37: movl $0,in_Debugger db> tr Debugger(c0237e83) at Debugger+0x37 panic(c0238a43,7,0,c5e4e45c,c0281d0c) at panic+0x74 rlist_free(c0281d08,0,7,f,c0abafc8) at rlist_free+0xfa swap_pager_freeswapspace(c5e4e45c,0,7,c5e4e45c,80000000) at swap_pager_freeswapspace+0x1b swap_pager_free_swap(c5e4e45c) at swap_pager_free_swap+0x85 swap_pager_dealloc(c5e4e45c,c5e51e84,c01f9a7e,c5e4e45c,80000000) at swap_pager_dealloc+0x8a vm_pager_deallocate(c5e4e45c,80000000) at vm_pager_deallocate+0x16 [deletia] exit1(c5df42e0,0,c5e51fb4,c021ab97,c5df42e0) at exit1+0x1fb exit1(c5df42e0,c5e51f94,0, 281236b0,0) at exit1 syscall(27,27,0,281236b0,bfbfdb18) at syscall+0x187 Xint0x80_syscall() at Xint0x80_syscall()+0x2c or...
