PCAP

Hi All,
We are using embedded tomcat version 9.0.38 in our application to transport
http/2 packets between 2 systems (h2c connection). All parameters used are the
tomcat defaults.
Tomcat port:1090

Issue :
For few streams we see that :
After processing requests successfully, tomcat does not send WINDOW_UPDATE
abruptly for the following HEADERS/DATA, due to which the client sends
RST_STREAM, also which tomcat has not acknowledged.

Since the issue has occured in production , we wont be able to test with the
latest version on tomcat .

Find attached the PCAP for reference:

Please help resolve this issue.

Thanks in advance !!

Thanks and Regards
Arshiya Shariff

The application was working fine with the same version since few months , so we
want to find the RCA as to why the issue has occurred . 
Was there any fix around this that went in post 9.0.38 so we can update the
same to the customer otherwise it is difficult to push the customer for an
upgrade.

There are several fixes to HTTP/2 window updates between version 9.0.38 and
9.0.56 (current latest). You can review the changes here
https://tomcat.apache.org/tomcat-9.0-doc/changelog.html and just do a quick
search for HTTP/2.

It is far easier for you to test this in your environment to see how/if the
issue is fixed than it would be for anyone else to test it. If we had tests
demonstrating a problem, we would fix the problem so the tests pass.

If you have a test that fails, please attach it to this report. If you do not
have a test that fails, it will be impossible for anyone to tell you whether or
not it is fixed.

--- Comment #5 from Arshiya  ---
As tomcat abruptly stops sending the WINDOW_UPDATE we are unable to reproduce
the issue in the test environment and find where the issue is . 
Can we have any scenarios to simulate a case where tomcat suddenly stops
sending WINDOW_UPDATE? Please let us know.
