Comment 4 for bug 1707220

It sounds like the proxy worker died trying to service the request, and each time the parent daemon spawned a new one... all the "Removing dead child <pid>" messages like http://logs.openstack.org/25/485225/5/check/gate-openstack-ansible-os_swift-ansible-func-centos-7/8ad31e6/logs/openstack/swift-proxy/swift/proxy-error.log.txt.gz#_Jul_24_19_20_58 seem to confirm that.

Are there any core dumps that get produced?

What's the config for the EC policy? ec_type / ec_num_data_fragments / ec_num_parity_fragments
