Tomcat Memory leak SolutionThis kind of problem is often encountered in the development, see the experience of the predecessorsReasons for Tomcat Memory overflowIn a production environment, Tomcat memory settings are not good enough to be prone to memory overflow.

Java is a garbage collection language, the advantage is that developers do not have to deliberately manage memory allocation, reduce the application due to local failure (segmentation fault) caused by the crash, while preventing the release of memory to the stack (heap), so the written code is more secure. Unfortunately, there are still a lot of logic in

Flexibility and freedom are a major feature of the C/C ++ language, which poses a challenge for C/C ++ programmers. When the program becomes more and more complex, the memory management will become more and more complex, and memory problems will occur if you are careful. Memory leakage is one of the most common memory

to be recycled, there is another object in use that holds its reference, causing it to not be recycled in the heap memory, which creates a memory leak;2. What is the impact of memory leaks on programs? Memory leaks are one of the main causes of application Oom. The Android
