http://issues.apache.org/bugzilla/show_bug.cgi?id=41749 Summary: Tomcat with APR using SSL spins CPU at 100% Product: Tomcat 5 Version: 5.5.20 Platform: Macintosh OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: Connector:Coyote AssignedTo: tomcat-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] I have a problem about once a week with a server which primarily serves HTTPS. The server continues to respond, but it pegs the CPU. The only remedy is to restart tomcat. The configuration is: Redhat EL 4. Dual AMD Operteron Processors. 1GB. 2.6.9-42.0.2.ELsmp openssl-0.9.7a-43.14 apr 1.2.8 tomcat-native 1.1.8 tomcat 5.5.20 thawte issued certificate. Here's the stacktrace for the only two threads which are doing any work. All other threads are waiting.
