Knowledge Collections for WebSphere Application ServerList of content for Out of Memory OOM1. Disabling AIO (Asynchronous Input/Output) java websphere tutorial native transport in WebSphere Application Server (1366862)IBM Support might request you to disable the AIO native transport code. In certain cases, this code can have a fairly large native out of memory error java lang outofmemoryerror nokia memory footprint, and if the application server is short on native memory, disabling the AIO native transport can increase the available address space for native memory.2. Troubleshooting native memory issues (1373312)There are two types of memory problems which will throw an OutOfMemoryError: If a Java object cannot be allocated or if there is no more memory available for

native code allocations (c malloc) or threads. The first case is called Java heap exhaustion and the second, a native memory issue. Finding the users of native memory can be a lengthy process, as there is no way of knowing which code allocated the native memory. There are no comparable heapdumps for native memory, so we have to use trial and error, going through each of the potential native memory users until we find the one that is causing the problem. Following are the most common causes of native memory issues in WebSphere Application Server, so you should try them first. They are all trying to reduce the native memory used 3. Potential native memory use in WebSphere Application Server thread pools (1368248)The WebSphere Application Server thread pools can leak ThreadLocal objects when threads are destroyed (java.lang.ThreadLocal). ThreadLocal objects can have a significant native memory component, so you can see a native memory leak if there is a ThreadLocal leak.4.

Answer To resolve the issue, increase the Java™ virtual machine (JVM) parameter MaxPermSize to 512M in the server.xml file of the created profile. Complete the following steps: Open the install_root/profiles/profile_name/config/cells/cell_name/nodes/node_name/servers/server_name/server.xml file search for genericJvmArgument. Scroll down towards the end of the file and find the genericJvmArguments property within the jvmEntries attribute. Add -XX:MaxPermSize=512m http://www.ibm.com/support/docview.wss?uid=swg21413980 as the last value for the genericJvmArguments parameter. For example:
