Subject RE: [users@httpd] Apache 2.2.32 failing F5 health check
Date Mon, 06 Feb 2017 20:34:08 GMT
This issue is different from the CR LF issue. We checked for any delimiters/spaces etc. The
F5 health checks work fine with 2.2.31 on the same server, without any change in the configuration,
but when we upgrade to 2.2.32, apache reports a 400 error.

Someone recently reported a subset of their F5 health checks were using LF line endings instead
of CR LF.
