Bug ID: 64859 Summary: Assertion errros org.apache.catalina.mapper.Mapper.internalMap(Mapper.j ava:744) Product: Tomcat 9 Version: 9.0.34 Hardware: All OS: Linux Status: NEW Severity: normal Priority: P2 Component: Catalina Assignee: dev@tomcat.apache.org Reporter: marcin.bo...@asseco.pl Target Milestone: ----- Created attachment 37538 --> https://bz.apache.org/bugzilla/attachment.cgi?id=37538&action=edit Full stacktraces for mentioned log entries We had observed the following assertion errors, total 356 cases. "java.lang.AssertionError at org.apache.catalina.mapper.Mapper.internalMap(Mapper.java:744)" Above errors were preceded by the two log info entries "org.apache.catalina.connector.CoyoteAdapter.checkRecycled Encountered a non-recycled request and recycled it forcedly. org.apache.catalina.connector.CoyoteAdapter$RecycleRequiredException" "org.apache.coyote.http11.Http11Processor.service Error parsing HTTP request header Note: further occurrences of HTTP request parsing errors will be logged at DEBUG level. java.lang.IllegalStateException: Unexpected state: headers already parsed. Buffer not recycled?" Full log entries are in the attachment. Assertion errors had occurred for 2 hours and then the problem disappeared. After a few hours, we had noticed another two cases this time not preceded by any connected log entries. After that, we restarted the problematic instance and the situation has not repeated anymore. Almost the same configuration and application are in use for weeks so it's rather not an issue. Application and installation: Spring Boot 2.0 + Vaadin 8 The application running in Kubernetes based on image tomcat:9.0.34-jdk8-openjdk-slim -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
