I haven't got it resolved yet, and I haven't got any more specific errors, either.
I have found a little more info, though. I've found out that it will allow me to view the indexes of my public html directories, but once I click on an actual file, it quits working. In other words, I can surf to
http://localhost/~cgrymala and it will show me that I have a file called info.php (something I put together based on a tutorial on setting up apache) and a directory called yabbfiles (I've placed the non-perl files from YaBB in there to test some things out). I can click on yabbfiles, and it opens up to show me the contents of that directory. However, if I click on one of the gif images that's in there, then I get the localhost connection broken error. When I check the error log, it shows a series of about 10-20 segmentation faults.
I'll keep searching.
I'm curious - if you have a newer version of libapr installed than the version of apache, could that possibly cause this problem? I downloaded a lot of rpm's to install things, but then happened upon apt. apt seems to install apache2.4.9, but I think my libapr is from v2.5.2. I'm not positive, but it seems that way (when I tried to install something using apt, it referred to the fact that my package required libapr 2.4.9, but I had libapr 2.5.2 installed.
EDIT - I forgot to mention - I did try apachectl configtest, and it kept telling me command not found, so I finally figured out that I really needed to try apache2ctl configtest and it simply returned "Syntax OK"
