We are using Resin Pro 3.0.24 and have noticed an intermittent problem that is rather weird. After the JVM has been running for a few days, we some times see the case where HTTP requests for certain files return a blank HTML page such as:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=Content-Type content="text/html; charset=windows-1252"></HEAD> <BODY></BODY></HTML> This seems to happen mostly with welcome files (index.html), and we see behavior such as: http://www.mydomain.com/mydirectory --> works fine http://www.mydomain.com/mydirectory/ --> returns this blank HTML page http://www.mydomain.com/mydirectory/index.html --> returns the blank HTML page as well http://mydomain.com/mydirectory/ --> works fine We run a Resin cluster and the weird part is that one JVM will return the blank page while the other ones work fine. When it happens, it seems to affect a lot of pages at once, but only on the one JVM. Restarting that JVM immediately fixes the problem... at least for a few days. Our welcome file list (in app-default.xml) looks normal: <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>index.php</welcome-file> </welcome-file-list> We are caching pages (in resin.conf): <resin:if test="${isResinProfessional}"> <cache path="cache" memory-size="10M"/> </resin:if> I don't want to turn on full debug logging because this happens in our production environment but only after the JVM has been running for several days. I would prefer not to slow down the server for a long time with the extra logging. Has anyone else seen anything like this or know what might be causing it? Thanks, Shane
