Hi @all, since I made an update of my spacewalk server (CentOS 5.3), no spacewalk packages involved, I can't shedule an update of my client systems anymore. Here is what I found in the tomcat log: 2009-07-06 14:02:43,914 [TP-Processor3] WARN com.redhat.rhn.common.localization.XmlResourceBundleParser - Duplicate message key found in XML Resource file: Users 2009-07-06 14:02:43,914 [TP-Processor3] WARN com.redhat.rhn.common.localization.XmlResourceBundleParser - Duplicate message key found in XML Resource file: Value 2009-07-06 14:02:43,914 [TP-Processor3] WARN com.redhat.rhn.common.localization.XmlResourceBundleParser - Duplicate message key found in XML Resource file: Waiters 2009-07-06 14:05:13,897 [TP-Processor8] WARN org.apache.struts.action.ActionMapping - Unable to find 'remotecmd' forward. 2009-07-06 14:05:13,900 [TP-Processor8] WARN org.apache.struts.action.RequestProcessor - Unhandled Exception thrown: class java.lang.IllegalStateException 2009-07-06 14:05:13,904 [TP-Processor8] ERROR com.redhat.rhn.frontend.servlets.SessionFilter - Error during transaction.
