This is what the log says in this part: If we didn't manage to set a syscall catchpoint, then we weren't able to figure out that address of the syscall instruction, and then everything breaks down. Everything past that first failure is just cascading failures. If the "catch syscall" didn't work, there's no point in continuing.
