What does long process mean?
Is the command line too long? Or do you mean that the process has been running
for too long now? 2 days isn't particularly long if this were the *parent*
process. If it isn't well.. that's a different case.

What does strace say?
What does mod_status say?

What is the server doing in general which would give us a hint of
what *could* be going on? -- Does it proxy? Run CGI? mod_php?
Does it serve and receive Dav on an SSL line, handling gzip
inflate  and deflate? etc....

Please realize that Apache httpd is a multipurpose server. So
a `ps` line doesn't tell us *anything* about what it's doing.

This on the other hand is more interesting.
Has this been there for as long as the process?

Also note that the connection IP is ::1 -- could this
just be the internal dummy connection? Or is this you?

Again: What does mod_status say?
