  • I use xwiki-enterprise-jetty-hsqldb-2.2-milestone-2.zip, and imported my old pages selectively. But now, the export utility failed to output an valid zip file. It should be around 20Mbytes, but now it returns a file of 11Mbytes. And there is an error in the log. In 2.1.1, I have the same problem if I select "backup pack(preserve author)". simba@wireless:~/XWiki Enterprise/webapps/xwiki$ 2010-01-29 21:46:17,158

  • I've been able to reproduce this problem easily in Confluence 3.3. Steps: # Create an Excel spreadsheet with data in a very high row number (the attached one has data in rows 1, 2, and 65536). This file can actually be quite small (41kb). One of our users actually did this by accident! # Attach spreadsheet to a page # Use the viewxls macro to display the spreadsheet on your page. Result: Most of the time, the page won't load - it times out or returns "Page Not Found". Sometimes it WILL load with a "viewxls: java.lang.OutOfMemoryError: Java heap space" error. Java VM Heap free space rapidly plummets (as reported by refreshing the System Info page of Confluence's Admin panel). The entire Confluence instance gets slower. Sometimes the entire Confluence installation stops responding for a little while (eventually it recovered itself). {noformat:title=sample stack trace} 2010-11-24 11:18:12,051 ERROR [TP-Processor6] [renderer.v2.components.MacroRendererComponent] processMacro Unexpected error formatting macro: viewfile -- url: /display/spacekey/pageTitle | page: 34709164 | userName: admin | referer: https://confluenceURL/display/spacekey/pageTitle | action: viewpage java.lang.OutOfMemoryError: Java heap space at java.util.Arrays.copyOf(Arrays.java:2882) at java.lang.AbstractStringBuilder.expandCapacity(AbstractStringBuilder.java:100) at java.lang.AbstractStringBuilder.append(AbstractStringBuilder.java:390) at java.lang.StringBuffer.append(StringBuffer.java:224) at java.io.StringWriter.write(StringWriter.java:84) at com.benryan.conversion.SpreadsheetConverter.writeHeaderStyles(SpreadsheetConverter.java:204) at com.benryan.conversion.SpreadsheetConverter.write(SpreadsheetConverter.java:65) at com.benryan.conversion.SpreadsheetConverter.convert(SpreadsheetConverter.java:395) at com.benryan.conversion.XlsConverter$1.doConversion(XlsConverter.java:42) at com.benryan.conversion.DocConverter.execute(DocConverter.java:59) at com.benryan.conversion.macro.ConverterMacro.execute(ConverterMacro.java:276) at com.atlassian.renderer.v2.macro.ResourceAwareMacroDecorator.execute(ResourceAwareMacroDecorator.java:51) at com.atlassian.renderer.v2.components.MacroRendererComponent.executeMacro(MacroRendererComponent.java:203) at com.atlassian.renderer.v2.components.MacroRendererComponent.processMacro(MacroRendererComponent.java:169) at com.atlassian.renderer.v2.components.MacroRendererComponent.makeMacro(MacroRendererComponent.java:67) at com.atlassian.renderer.v2.components.WikiContentRendererHandler.handleMacro(WikiContentRendererHandler.java:18) at com.atlassian.renderer.v2.WikiMarkupParser.makeMacro(WikiMarkupParser.java:120) at com.atlassian.renderer.v2.WikiMarkupParser.handlePotentialMacro(WikiMarkupParser.java:105) at com.atlassian.renderer.v2.WikiMarkupParser.parse(WikiMarkupParser.java:60) at com.atlassian.renderer.v2.components.MacroRendererComponent.render(MacroRendererComponent.java:46) at com.atlassian.renderer.v2.V2Renderer.render(V2Renderer.java:53) at com.atlassian.renderer.v2.plugin.PluggableV2Renderer.render(PluggableV2Renderer.java:30) at com.atlassian.renderer.v2.V2RendererFacade.convertWikiToXHtml(V2RendererFacade.java:57) at sun.reflect.GeneratedMethodAccessor393.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.springframework.aop.support.AopUtils.invokeJoinpointUsingReflection(AopUtils.java:304) at org.springframework.aop.framework.ReflectiveMethodInvocation.invokeJoinpoint(ReflectiveMethodInvocation.java:182) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:149) at com.atlassian.spring.interceptors.SpringProfilingInterceptor.invoke(SpringProfilingInterceptor.java:16) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:171) at org.springframework.transaction.interceptor.TransactionInterceptor.invoke(TransactionInterceptor.java:106) {noformat}
