    While trying to add a top-level community, or a sub-community to our DSpace community, we received an Internal Server Error. Looking through the logs, I noticed that trying to add a community causes Oracle to throw a ORA-0001 error: 2011-01-07 09:14:32,848 WARN org.dspace.app.webui.servlet.DSpaceServlet @ blensch@georgiasouthern.edu:session_id=1232A007BC7400C3524C38F490C87A6B:ip_addr=141.x.x.x:database_error:java.sql.SQLException\colon; ORA-00001\colon; unique constraint (DSPACE_USER.SYS_C007905) violated java.sql.SQLException: ORA-00001: unique constraint (DSPACE_USER.SYS_C007905) violated at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112) at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:331) at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:288) at oracle.jdbc.driver.T4C8Oall.receive(T4C8Oall.java:745) at oracle.jdbc.driver.T4CPreparedStatement.doOall8(T4CPreparedStatement.java:219) at oracle.jdbc.driver.T4CPreparedStatement.executeForRows(T4CPreparedStatement.java:970) at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(OracleStatement.java:1190) at oracle.jdbc.driver.OraclePreparedStatement.executeInternal(OraclePreparedStatement.java:3370) at oracle.jdbc.driver.OraclePreparedStatement.executeUpdate(OraclePreparedStatement.java:3454) at org.apache.commons.dbcp.DelegatingPreparedStatement.executeUpdate(DelegatingPreparedStatement.java:102) at org.apache.commons.dbcp.DelegatingPreparedStatement.executeUpdate(DelegatingPreparedStatement.java:102) at org.dspace.storage.rdbms.DatabaseManager.execute(DatabaseManager.java:1429) at org.dspace.storage.rdbms.DatabaseManager.update(DatabaseManager.java:781) at org.dspace.handle.HandleManager.createHandle(HandleManager.java:172) at org.dspace.content.Community.create(Community.java:205) at org.dspace.content.Community.createSubcommunity(Community.java:845) at org.dspace.app.webui.servlet.admin.EditCommunitiesServlet.processConfirmEditCommunity(EditCommunitiesServlet.java:520) at org.dspace.app.webui.servlet.admin.EditCommunitiesServlet.doDSPost(EditCommunitiesServlet.java:237) at org.dspace.app.webui.servlet.DSpaceServlet.processRequest(DSpaceServlet.java:147) at org.dspace.app.webui.servlet.DSpaceServlet.doPost(DSpaceServlet.java:105) at javax.servlet.http.HttpServlet.service(HttpServlet.java:710) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:269) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.dspace.app.webui.filter.RegisteredOnlyFilter.doFilter(RegisteredOnlyFilter.java:98) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:215) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.dspace.utils.servlet.DSpaceWebappServletFilter.doFilter(DSpaceWebappServletFilter.java:112) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:215) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:210) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:172) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:108) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:151) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:875) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:665) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:528) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:81) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:685) at java.lang.Thread.run(Thread.java:636) Has anyone else seen this error before, or lend any insight on how to fix this problem?
