--- Comment #3 from Evgenij Ryazanov <kat...@gmail.com> --- 1-3 errors per day under load. At least it has a stack trace. It's not easy to simulate I/O error at right time to reproduce it. There are too many assorted messages in logs. After some filtering and search I see that this exception usualy happends just a two or three seconds after org.apache.coyote.http11.Http11Processor service INFO: Error parsing HTTP request header Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level. java.lang.IllegalStateException: Unexpected state: headers already parsed. Buffer not recycled? at org.apache.coyote.http11.Http11InputBuffer.parseHeaders(Http11InputBuffer.java:550) org.apache.coyote.http11.Http11Processor endRequest SEVERE: Error finishing response java.lang.NullPointerException at org.apache.coyote.http11.Http11OutputBuffer.commit(Http11OutputBuffer.java:351) See attachment for full traces. So all of them may be related. There are many such errors in service and endRequest, but only a few at Buffer.position(). Sometimes it has a longer stack trace (see sample in the same attachment). -- 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
