In a previous blog post Linux kernel module, a way to find out about memory leaks >> , I introduced a method of finding kernel memory leaks. This is a few months, and customers complain: using the product 5 days or so, the SUSE server due to memory exhaustion and crash. O my God, don't, run on my machine good WOW (programmers commonly used sayings hehe). So let's take a look at how the hard-pressed blogger determines the problem and finds the problem
