Naveed, Funny, we just started getting the same error intermittently today, as well. For us it's only happening once every few hours.
I've been digging through our logs for more info. For us, these errors *always* occur from the same web crawler/bot, which is identifying itself as: "Yeti/0.01 (nhn/1noon, [EMAIL PROTECTED], check robots.txt daily and follow it)" I've been searching around on this bot now. There's some indications that this may just be a bad bot: http://www.webmasterworld.com/search_engine_spiders/3449200.htm I'm not sure if this is the same problem you are seeing, Naveed? - Tim NS Hashmi, Information Systems and Computing wrote: > Hi > > Does anyone know what the error below relates to? we've had these errors > occurring intermittently today - perhaps tomcat needs a re-start? > > 2007-11-20 17:04:13,610 WARN > org.dspace.app.webui.servlet.InternalErrorServlet @ > :session_id=348891038422FF0478DC37B8F866ADA3:internal_error:-- URL Was: > http://deneb.lib.bris.ac.uk/dspace/handle/1983/914 > -- Method: GET > -- Parameters were: > > java.lang.IllegalArgumentException: 11 Aug 2007 11:13:22 GMT > at > org.apache.coyote.tomcat5.CoyoteRequest.getDateHeader(CoyoteRequest.java:1887) > at > org.apache.coyote.tomcat5.CoyoteRequestFacade.getDateHeader(CoyoteRequestFacade.java:426) > at > org.dspace.app.webui.servlet.HandleServlet.doDSGet(HandleServlet.java:157) > at > org.dspace.app.webui.servlet.DSpaceServlet.processRequest(DSpaceServlet.java:151) > at > org.dspace.app.webui.servlet.DSpaceServlet.doGet(DSpaceServlet.java:99) > at javax.servlet.http.HttpServlet.service(HttpServlet.java:697) > at javax.servlet.http.HttpServlet.service(HttpServlet.java:810) > at > org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:237) > at > org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:157) > at > org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:214) > at > org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveContext.java:104) > at > org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:520) > at > org.apache.catalina.core.StandardContextValve.invokeInternal(StandardContextValve.java:198) > at > org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:152) > at > org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveContext.java:104) > > 9517,11 99% > at > org.dspace.app.webui.servlet.DSpaceServlet.doGet(DSpaceServlet.java:99) > at javax.servlet.http.HttpServlet.service(HttpServlet.java:697) > at javax.servlet.http.HttpServlet.service(HttpServlet.java:810) > at > org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:2 > 37) > at > org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:157) > at > org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:214) > at > org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveContext.java:104) > at > org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:520) > at > org.apache.catalina.core.StandardContextValve.invokeInternal(StandardContextValve.java:198) > at > org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:152) > at > org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveContext.java:104) > at > org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:520) > at > org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:137) > at > org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveContext.java:104) > at > org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117) > at > org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveContext.java:102) > at > org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:520) > at > org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) > at > org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveContext.java:104) > at > org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:520) > at > org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:929) > at > org.apache.coyote.tomcat5.CoyoteAdapter.service(CoyoteAdapter.java:160) > at > org.apache.jk.server.JkCoyoteHandler.invoke(JkCoyoteHandler.java:296) > at > org.apache.jk.common.HandlerRequest.invoke(HandlerRequest.java:372) > at org.apache.jk.common.ChannelSocket.invoke(ChannelSocket.java:694) > at > org.apache.jk.common.ChannelSocket.processConnection(ChannelSocket.java:626) > at > org.apache.jk.common.SocketConnection.runIt(ChannelSocket.java:807) > at > org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:644) > at java.lang.Thread.run(Thread.java:595) > > Thanks, > > Naveed > -------------------------------------------------------- > Naveed Hashmi > Information Systems and Computing > University of Bristol > > > > > ------------------------------------------------------------------------- > This SF.net email is sponsored by: Microsoft > Defy all challenges.
