Problem solved. Just wanted to post back so folks having the same
problem might benefit from my wasted day of troubleshooting.
Turned out that a few files in my FSFS repo had gotten corrupted. I
had backups (thankfully), so I just replaced those couple files
giving me problems in 'svnadmin verify' with the backups, and that
was that. There was one other file giving me problems (turned up
as: "
svn: E175002: REPORT of '/svn/reponame/!svn/me': Could not
read chunk size: Secure connection truncated
(https://mycomp:53239)" ). I looked in the windows event
logs for the VisualSVN Server events, and turned out there were
permission problems. I changed the permissions on the corresponding
file in the repo/db/revs file to match all the other files in there
(it must have gotten corrupted too), and now i'm running great.
Hope someone can benefit from my experience.
