may able to start a server with Java heap as high as 2.3GB but don't expect the application to last long. Due to various activities in non heap memory space such as GC (Garbage http://eai.ittoolbox.com/groups/technical-functional/webmethods-l/outofmemory-heap-error-1862873 Collection), Threads, byte code to native compilations etc., a server is likely to crash with a native memory error. Therefore, you need to strike a balance between adequate memory for the application to run without running out of heap memory and JVM to perform house keeping tasks without exhausting native memory space. Here are some guidelines on managing memory requirements for webMethods servers (IS and MWS, 7.1.2) on 32 bit https://smudali.wordpress.com/2010/10/19/memory-management-and-troubleshooting-for-webmethods%C2%A0servers/ operating systems: Know your application memory requirements. This is very important because people generally prefer to give as much memory as possible to Java heap. After all, giving more memory, surely will benefit performance. Right? Not quite. As outlined above, we are juggling with 3 / 2 GB of memory on a 32bit system and more heap memory means less native memory. Therefore, it is important to monitor the memory requirements for the application and allocate accordingly. Use server class hardware to run servers. Hotspot server system is automatically detected on server class machines. The server system is optimal where overall performance is critical and client system is suitable for applications which require fast startup times or small footprints. Differences between the two systems include the compilation policy, heap defaults, and inlining policy. For instance, compiler threshold is 10000 for server mode and 1500 for client mode. The high threshold for server system is required for optimal optimization Use JVM options. Use them with caution as they may have an adverse effect for inappropriate usage. Some useful options: Java Heap size: -Xms and -Xmx Perm memory: -XX:MaxPermSize Young generation heap size: -XX:NewRatio GC algorithm: e.g., -XX:+UseConcMarkSweepGC, -XX:+UseParNewGC Dump heap on memory error: -XX:+HeapDumpOnOutOfMemoryError Dump file: -XX:HeapDumpPath=

Apparently this can occur after redeploying an application a few times. What causes it and what can be done to avoid it?

See my related question: stackoverflow.com/questions/1996088/… You may still have a memory leak, e.g. classes are not garbage collected because your WebAppClassLoader is not garbage collected (it has an external reference that is not cleared). increasing the PermGen will only delay the OutOfMemoryError, and allowing class garbage collection is a precondition, but will not garbage collect classes if their class loader still has references to it. –Eran Medan Jan 14 '10 at 11:48 I got this error at adding display taglib. Removing so also solved the error.
