http://nagoya.apache.org/bugzilla/show_bug.cgi?id=18174 "servlet instance for Invoker.scroll unavailable" continuously logged by Tomcat Summary: "servlet instance for Invoker.scroll unavailable" continuously logged by Tomcat Product: Tomcat 4 Version: 4.1.12 Platform: PC OS/Version: Windows NT/2K Status: NEW Severity: Normal Priority: Other Component: Catalina AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] I had been running Tomcat 4.1.12 on an NT4.0 sp6+, for about one month when Tomcat began producing the following error in its log files. It occurs continuously each day while the web apps using servlets are being accessed. NOWHERE in my apps is there a servlet "scroll", nor is there any reference to one. Additionally, I have set debug="0" in the config .xml files. I have installed Tomcat 4.1.12 onto my Win2000 PC but only sporadically get this message. While the occurrence of this does not interrupt my web apps, I'm concerned that the log files are daily growing to 8 - 14mb. Also, it is not normal behaviour. Is there a servlet in Catalina called "scroll" or is this somehow a problem in my apps or my Sun Java packages? Any help that could be provided would be greatly appreciated.
