The Cb Response Server is unable to accept binaries from sensors since it is unable to write to its working directory /var/cb/nginx/client_temp. Sensors continue to attempt to upload the binary to the server causing network bandwidth problems. This can occur after a server move where permissions were not correctly copied over.
