Hi All,
I have been debugging HTTP2 stall connection by Chromium browser (Request is
being stalled). During continuous requests, the chrome browser is stalling due
to a PING Request error as shown below the post.
t=486451 [st=312960] HTTP2_SESSION_CLOSE
--> description = "Failed ping."
--> net_error = -352 (ERR_HTTP2_PING_FAILED)
t=486452 [st=312961] HTTP2_SESSION_POOL_REMOVE_SESSION
Tomcat Version: Apache Tomcat/9.0.43
Please refer to the following for more details:
https://groups.google.com/a/chromium.org/g/chromium-discuss/c/4u136_Sjo1c
https://bugs.chromium.org/p/chromium/issues/detail?id=1225774
For the PING Frame sometime, to request, it is failing to reply in timely
manner and after enabling FINE tracing on the tomcat I am able to get following
Exception:
Exception in thread "https-jsse-nio-127.0.0.1-8443-exec-10"
java.lang.NullPointerException
