Sudheer Vinukonda created TS-3778:
-------------------------------------
Summary: Memory leak caused by the TS-3640.
Key: TS-3778
URL: https://issues.apache.org/jira/browse/TS-3778
Project: Traffic Server
Issue Type: Bug
Components: Core
Reporter: Sudheer Vinukonda
TS-3640 removed the code that was otherwise always doing a half-close on the
ua_session for POST transactions that had error'ed on the origin connection. It
seems like this allows to preserve the keep alive client connections as well as
drain any body that was still in the buffers. This piece of code is very
important when there's heavy POST involved.
On a related note, I see that TS-3640 was added to fix regressions caused by
TS-3584. But, TS-3584 looks questionable to me too.
We have observed heavy memory leaks with hosts crashing in less than a day
after TS-3640's commit has been deployed (We are in the process of confirming
that the problem is completely resolved by reverting TS-3640. The memory looks
stable enough after about 12 hrs run without TS-3640, running a little longer
to be safe)
