There is a webpage which takes user input,builds a query and sends it to Lucene Database(20GB in size) and displays the result in a downloadable textfile.However this functionality is not working properly and I get the following exception after I submit the user Input.

message "PermGen space"), it simply means the JVM ran out of memory. When it occurs, you basically have 2 options: Solution 1. Allow the JVM to use more memory With the -Xmx JVM argument, tomcat java.lang.outofmemoryerror: java heap space you can set the heap size. For instance, you can allow the JVM to how to increase heap size in java use 2 GB (2048 MB) of memory with the following command: Configuring java heap size Shell $ java -Xmx2048m ... 123 $ javax.servlet.servletexception: java.lang.outofmemoryerror: gc overhead limit exceeded java -Xmx2048m ... Solution 2. Improve or fix the application to reduce memory usage In many cases, like in the case of a memory leak, that second option is the only good solution. A memory http://stackoverflow.com/questions/17272821/java-lang-outofmemoryerror-java-heap-space-how-to-resolve-this-error leak happens when the application creates more and more objects and never releases them. The garbage collector cannot collect those objects and the application will eventually run out of memory. At this point, the JVM will throw an OOM (OutOfMemoryError). A memory leak can be very latent. For instance, the application might behave flawlessly during development and QA. However, it suddenly throws a OOM after several days in production at customer site. http://opcodesolutions.com/tech/solve-java-lang-outofmemoryerror-java-heap-space/ To solve that issue, you first need to find the root cause of it. The root cause can be very hard to find in development if the problem cannot be reproduced. Follow those steps to find the root cause of the OOM: Step 1. Generate a heap dump on OutOfMemoryError Start the application with the VM argument -XX:+HeapDumpOnOutOfMemoryError. This will tell the JVM to produce a heap dump when a OOM occurs: Trigger heap dump on OOM Shell $ java -XX:+HeapDumpOnOutOfMemoryError ... 123 $ java -XX:+HeapDumpOnOutOfMemoryError ... Step 2. Reproduce the problem Well, if you cannot reproduce the problem in dev, you may have to use the production environment. When you reproduce the problem and the application throws an OOM, it will generate a heap dump file. Step 3. Investigate the issue using the heap dump file Use VisualVM to read the heap dump file and diagnose the issue. VisualVM is a program located in JDK_HOME/bin/jvisualvm. The heap dump file has all information about the memory usage of the application. It allows you to navigate the heap and see which objects use the most memory and what references prevent the garbage collector from reclaiming the memory. Here is a screenshot of VisualVM with a heap dump loaded: This will give you ve

Someone might have set off a lot of TNT. If you are launching the server with a batch file, change it to java -Xms2G -Xmx2G minecraft_server.jar or something like that so that Minecraft have more memory. Also, you might want to open the map with a world editor to make sure that there isn't java heap space lots of TNT somewhere.

Basically, to give Java more memory, edit the -Xmx1G from your Bukkit .bat launcher to -Xmx2G or something similar. I would again advise you to try to check for TNT or other things that may cause the server to crash.
