Integration of MyEclipse2014 and jprofiler to analyze the memory usage of the webproject Today, I went to demonstrate a web system. During the demonstration, the system suddenly reported a 500 error. I logged on to the server and found that the cpu usage reached 103%. I immediately killed the process and restarted it, to complete the demo process. after the demo is completed, immediately start the Memory Leak-related work to ensure that this emergency

JProfilerThe memory View session provides a dynamic update view of memory usage and an Information view of the allocation point. All views have several clustering layers and can display existing objects and objects as garbage collection objects.

In recent work, jprofiler is used to solve the memory leakage problem. Now we have recorded the detection steps and some analysis results, and we can use them as a reference when we encounter similar problems in the future. Running Environment: tomcat6, jdk6, jprofiler8 Memory leakage: 1. when performing some batch operations on the server, it is found that the memory only rises or falls; even after GC, the memory cannot be completely released; 2. unl

Later, the use of tool commands to analyze the problem is due to insufficient memory leading to the GC because GC Task thread occupies a higher CPU.
