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 http://www-01.ibm.com/support/docview.wss?uid=swg21647230 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 http://www.ibm.com/support/docview.wss?uid=swg27021664 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.

Out of memory (OOM) is an often undesired state of computer operation where no additional memory can be allocated for use by programs or the operating system. Such a system will be unable to load any additional programs, and since many programs may load additional data into memory during execution, these will cease to function correctly. This usually occurs because all available memory, including disk swap space, has been allocated. Contents 1 History 2 Out of Memory Management 3 Per-process memory limits 4 References 5 External links History[edit] Historically, the out of memory condition was more common than it is now, since early computers and operating systems were limited to small amounts of physical random-access memory (RAM) due to the inability of early processors to address large amounts of memory, as well as cost considerations. Since the advent of virtual memory opened the door for the usage of swap space, the condition is much more rare. Almost all modern programs expect to be able to allocate and deallocate memory freely at run-time, and tend to fail in uncontrolled ways (crash) when that expectation is not met; older ones often allocated memory only once, checked whether they got enough to do all their work, and then expected no more to be forthcoming. Therefore, they would either fail immediately with an "out of memory" error message, or work as expected.[citation needed] Early operating systems such as MS-DOS lacked support for multitasking. Programs were allocated physical memory that they could use as they needed. Physical memory was often a scarce resource, and when it was exhausted by applications such as those with Terminate and Stay Resident functionality, no further
