Hello, Can anybody shed any light on this problem: This is a weird problem. It happens reliably on the client site within a short period of time, but we have yet to see it happen on our internal development server. On our client's server, we have Domino 5.0.6a running alongside Tomcat 3.2.2 using Tomcat Redirector 1.0.2. We have generated our own SSL certificate for test purposes using Domino's built-in tools. We configured Domino to use the generated certificate. Then we restarted Domino. Then, we fired up a browser, started browsing our Tomcat hosted JSPs using HTTPS and within a short period of time, we get the Domino's Application Error dialog box telling us that Tomcat 3.2 Java.exe has developed a problem and a NOTES.RIP file has been generated. When we click on the Done button, both the Tomcat and Domino windows disappear. When we clear the field in the Server Configuration document specifying the path of the SSL certificate, save and close the document and restart Domino, we can browse our JSPs using plain old HTTP and Tomcat becomes much more stable. Have you heard of this before? Any ideas as the underlying cause and how we might resolve this? One possibly salient fact- on our client's server, in the Tomcat window, the following message (approximately) is continuously being generated: Ctx 400 R <> null We occasionally get this on our internal server, but it is always occurring on the client's server Regards, Pat Bottomley
