topic Out of memory errors in Alfresco Archive https://connect.hyland.com/t5/alfresco-archive/out-of-memory-errors/m-p/63083#M39499 <HTML><HEAD></HEAD><BODY><SPAN>I'm running Alfresco 1.4 community on JBoss 4.0.5GA on Fedora Core 4 running Java JDK 1.5.0_10 on a server with 2 gb physical ram and 4 gb swap space. My database is MySql 4.1.20. In addition to Alfresco I have 2 othe application using JBoss on this server. I start JBoss in the "default" configuration with thies java memory options:</SPAN><BR /><BR /><SPAN>JAVA_OPTS="-Xms512m -Xmx1536m</SPAN><BR /><BR /><SPAN>I have expanded -Xmx by 256m from the installation default in the past few days to wee if the problem would go away.</SPAN><BR /><BR /><SPAN>Normally I seem to have this Java memory usage (show by the top command:</SPAN><BR /><BR /><SPAN>Mem:&nbsp;&nbsp; 2074912k total,&nbsp; 1983168k used,&nbsp;&nbsp;&nbsp; 91744k free,&nbsp;&nbsp; 168696k buffers</SPAN><BR /><SPAN>Swap:&nbsp; 4096368k total,&nbsp;&nbsp; 305160k used,&nbsp; 3791208k free,&nbsp;&nbsp; 846584k cached</SPAN><BR /><BR /><SPAN>What happens to me is that I have frequent Out Of Memory Errors in JBoss and it only happens when Alfresco is being used. I am not able to duplicate the problem except to say that if Alfresco is used long enough during the day it will happen. On 2 occasion I was using Alfresco myself when the error happened and what I was doing was:</SPAN><BR /><BR /><SPAN>a) Uploading a document rith after I put in the meta data and hit the button to continue (I can't remember its name right now).</SPAN><BR /><SPAN>b) Trying to edit the space user permissions in a nested space which had "editor" rights. As soon as I hit the "edit" button it crashed.</SPAN><BR /><BR /><SPAN>However, this is not reproducible.</SPAN><BR /><BR /><SPAN>This is the error message the browser showed when I happened to do (b):</SPAN><BR /><BR /><SPAN>javax.faces.FacesException: org/eclipse/jdt/internal/compiler/util/Messages$MessagesProperties</SPAN><BR /><SPAN>org.apache.myfaces.context.servlet.ServletExternalContextImpl.dispatch(ServletExternalContextImpl.java:421)</SPAN><BR /><SPAN>org.apache.myfaces.application.jsp.JspViewHandlerImpl.renderView(JspViewHandlerImpl.java:234)</SPAN><BR /><SPAN>org.apache.myfaces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:352)</SPAN><BR /><SPAN>javax.faces.webapp.FacesServlet.service(FacesServlet.java:106)</SPAN><BR /><SPAN>org.alfresco.web.app.servlet.AuthenticationFilter.doFilter(AuthenticationFilter.java:73)</SPAN><BR /><SPAN>org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)</SPAN><BR /><BR /><SPAN>This does not seem very useful.
