----------------------------------
Summary: High CPU utilization when processing Http/2 traffic
Key: TS-3413
URL: https://issues.apache.org/jira/browse/TS-3413
Project: Traffic Server
Issue Type: Bug
Components: HTTP/2, Performance
Reporter: Susan Hinrichs
This was discovered while tracking the segmentation fault in TS-3405 and the
original discussion is there.
Running ATS in forward transparent mode with Http/2 support enabled. After a
few page views, ATS gets into a state where it is consistently using more than
100% CPU. I think what is happening is that the origin server is closing the
connection (we get a TS_EVENT_VCONN_EOS in FetchSM). FetchSM sends a BODY_DONE
to Http2ClientSession but the http_vc (origin socket?) is never closed, so with
each poll interval the EOS is reported again and again.
