Great!! With tomcat-9.0-20210701.191821-3270 in our environment it seems to
be stable without any RST_STREAMs.
Excellent. Thanks for confirming the fix.
When will you release this version?
Releases happen ~monthly. We aim for early in the month and typically
have the release available some time in the second week.
There is a set of releases in progress at the moment but they do not
include these fixes. The next set of releases is scheduled for August.
It isn't unusual for us to skip the August release as folks are often on
holiday but given the severity of this issue, my current intention is to
try and do an August release.

Tx.
It looks like there are multiple issues going on here then - in
additional to the sendfile issue I already fixed. I'll fix the issue I'm
currently seeing and then try again to recreate the issue you are
seeing. I'll keep the thread updated with how I get on.
I've found and fixed a couple of issues with the management of the
connection flow control window. The fixes are consistent with the
workarounds you described (reduce the size of the stream flow control
window, reduce concurrent streams).
The fixes are included in the latest snapshot from:
https://repository.apache.org/content/groups/snapshots/org/apache/tomcat/tomcat/9.0-SNAPSHOT/
(tomcat-9.0-20210701.191821-3270 or later)
If you are able to test the snapshot in your dev environment, it would
be very helpful to know if the issue has been resolved.
