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. -- Eric Covener covener@xxxxxxxxx --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
