This is after two weeks on a system with maybe just a few thousand documents, of varied size and with relatively light use. Restart the alfresco service and in another two weeks we're in the same state. Within a few hours of the heap dump we hit OutOfMemoryErrors for java heap space.</SPAN><BR /><BR /><SPAN>I'm assuming ehcache using a few hundred MB is normal and the issue is within lucene? Any help would be appreciated.</SPAN></BODY></HTML> Mon, 10 Sep 2012 10:22:45 GMT cs02rm0 2012-09-10T10:22:45Z Alfresco 3.4.7 OutOfMemoryError - possibly lucene https://connect.hyland.com/t5/alfresco-archive/alfresco-3-4-7-outofmemoryerror-possibly-lucene/m-p/258764#M211894 I'm seeing the following when looking at a heap dump in Eclipse MAT from a JVM with a 3GB Xmx on a node that only has alfresco.war in the tomcat webapps.~2000 instances of org.apache.lucene.store.RAMFile 30% ~33000 instances of org.apache.lucene.index.TermInfosReader$ThreadResources 25% (680MiB) 1 i Mon, 10 Sep 2012 10:22:45 GMT https://connect.hyland.com/t5/alfresco-archive/alfresco-3-4-7-outofmemoryerror-possibly-lucene/m-p/258764#M211894 cs02rm0 2012-09-10T10:22:45Z Re: Alfresco 3.4.7 OutOfMemoryError - possibly lucene https://connect.hyland.com/t5/alfresco-archive/alfresco-3-4-7-outofmemoryerror-possibly-lucene/m-p/258765#M211895 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><SPAN>do you run some custom java code.
