That should be normal behavior...
Yes I understand that valid system changes will be notified in the next rkhunter report.

It seems that the report about /usr/sbin/httpd is simply a false positive of a valid process.
If Charlie doesn't know why rkhunter generated it, then it's not likely any of us will know.
As it appears to be a "one off", I'll ignore it with safety.
Thanks all.
