Susan Hinrichs commented on TS-4813:
------------------------------------
I see in our production version of HttpTunnel::producer_handler has a if
(p->alive) check in the TIMEOUT/ERROR event case. So that explains why we
don't see this problem. Will poke around to see if this is something that we
added but didn't make it to open source or if it was code explicitly removed
from open source.
