How to prevent memory leakage of your web applications

Memory is a vital component of any computer or web application. A memory leak occurs when there is an unused memory space held by a program, process or an object that itself has lost its validity.  When the object that as assigned a memory during the execution of the program is unable to release the memory block back into the pool of memory it is wastage of resource. This is a drawback that every web application needs to avoid. The code that is being executed for obtaining the dynamic pages may contain objects in the back side program. If this program contains objects that become inaccessible we identify the state to be in a memory leak.

This state has to be avoided in any case because, we know that memory is a stringent element in the world of computing. In internet or online application the memory has to use more judiciously that is why the dynamic memory allocation and release of memory blocks are required so as to obtain greater amount of memory when the previous allocation expires. If this process is not carried out fruitfully, it may lead to a complete exhaustion.

The majority of the web applications that are built today are on the Java platform. J2EE is specifically the mode in which the web applications work. Now Java being an object oriented language uses objects and the objects are assigned memory blocks during the execution of any process.

If the processes are using exhaustible amount of memory the web application may come to stand still due to lack of memory, therefore the memory leak is a symptom that has to be understood and diagnosed before it becomes malicious affects the system.


Apache tomcat the web application server has the feature which helps it to detect and prevent memory leak in your web application built on any open source platform. The memory leak detection feature of Tomcat enable you to avoid situations when the error message such as “out of memory” is thrown by the web application. Java itself has the features whereby you can release the unused memory that was previously held by a process but since the termination of the process the memory is released back into the pool for future use by any other process.

When you are trying to find about the origin of such an error as mentioned above you must try to reflect upon the fact that memory leak may have its origin in your code itself. The error message in most of the cases is thrown by the web application server that resides in the container.

The garbage collection feature has a lot of power that can help any java or object oriented program to free its memory from the clasps of an expired process thereby accumulate the unused memories. Once any process expires, while writing the Java code, you must pass the Garbage collector, which would free the process of the unused memory chunks. In most cases this method is able to solve the problem that leads to the error. Sorting out with the data structure and the coding along with proper synchronization of the database would let you resolve the anomalies thrown up.
