ANY REPLY MADE TO THIS MESSAGE WILL NOT BE COLLECTED AND� INSERTED IN THE BUG DATABASE. http://issues.apache.org/bugzilla/show_bug.cgi?id=37150 Summary: denial of service on many and long requests on v5.5.x Product: Tomcat 5 Version: 5.5.0 Platform: PC OS/Version: Linux Status: NEW Severity: major Priority: P2 Component: Catalina AssignedTo: tomcat-dev@jakarta.apache.org ReportedBy: david.maciejak@gmail.com Hi, I find some time to try to understand why sometimes my tomcat burns the CPU The fact: with long request (for example complex jsp or big dir listing) and if there is more than 1 simultaneous connection (is easy to reproduce the case with many connections); catalina stop responding, java takes all the CPU! I have tested that with default conf (perhaps there are some parameters to tune), I have create many files in a directory and many threads trying to get the directory listing. Tomcat version from 5.5.0 to 5.5.11 included are vulnerable, 5.5.12 seems to be ok. I have not tested older version. Have I missed something in the conf ? cheers David Maciejak -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscribe@tomcat.apache.org For additional commands, e-mail: dev-help@tomcat.apache.org
