[GitHub] [tomcat] bmistry13 opened a new pull request #431: Bug 65426 - HTTP2 Request is Stalled due to Exception on Tomcat. (PING FRAME)

bmistry13 opened a new pull request #431:
URL: https://github.com/apache/tomcat/pull/431


   Hello Tomcat Team,
   
   I am getting STALLED requests for PING FRAME occasionally and the chrome browser gets stuck for a long period of time.  It was due to the parent stream being null.  Since PING request is stream-id 0.  The parent is NULL. I was getting NPE.
   
   Here is Bug: https://bz.apache.org/bugzilla/show_bug.cgi?id=65426

   @markt-asf ,  Thank you I have tested it works with 9.0.50.   What could cause the following?  HTTP2 request gets stalled due to reset:
   
   I am occasionally  running into following exception:
   
   ```

   This PR will not be applied because:
   1. It addresses the symptom, not the root cause
   2. The root cause was fixed in 10.0.5, 9.0.45 and 8.5.65
