Open Files problem caused by requests for jsp pages
Hello world :) We're running a JSP application, and upgraded our plattform from Tomcat 3.1 to 3.2.1, and we're running into a 'open files' problem. The symptom is: it runs for a while, until all available file handles are in use - which causes the underlaying FeeBSD to refuse any further request for a file handle (even for a login). The system can be "switched" back to a normal state by killing the Java VM, which implies, that all file handles in use by Tomcat, are released. In Bugzilla, we found bug #134 which is to be fixed with Tomcat 3.2.2 - but our problem still occurs under Tomcat 3.2.2b1! The system we use (FreeBSD and Linux) issues a "too many open files" error after our webApp runs for a while. The "lsof" command shows that our project specific jar-files (the ones in webapps/myProject/WEB-INF/lib) are opened very very often. It seems that each request for a jsp page causes the engine to open the jar-files once again. This behaviour doesn't occur under Tomcat 3.1. Here no additional files are opened for each request. Does anybody has the same problem, or does anybody know a solution for this? Please let me know! Thank you! For several reasons, I want to avoid a fallback to Tomcat 3.1 mit freundlichen Grüßen Ihre 1822direkt Daniel Zuck _ Daniel Zuck 1882222 DV & Technik 111 8 8 2 2 2 2 1822direkt 1 8 8 2 2 Borsigallee 19 188 2 2 60608 Frankfurt am Main1 8 8 2 2 Tel: 069/94170-152; FAX: -199 1 8 8 2 2 mailto:[EMAIL PROTECTED]111 88 direkt __ Financial Times Deutschland, Telebörse und Focus Money sind sich einig: Die 1822direkt ist die Direktbank mit den zufriedensten Kunden Deutschlands.
