How to reproduce the issue

The original issue was discovered when the 404 error output of the rlm_rest module was concatenated using %{Module-Failure-Message[*]} in an attempt to write it to a log file.

The 404 content was the default NGINX 404 error page.

Each line seemed to be significantly truncated in the log output.

the xlat buffers in v3 are generally fixed-size, i.e. 256 bytes or 1024 bytes. We can increase ehgtir size, but we can't fix the underlying issue.
