I would expect it to work although we do not get many reports of
Subversion on Solaris so it is possible there is a bug. Subversion 1.7
is old.

We did have a Solaris buidbot running Solaris 10 and it ran the
regression tests over svn:// with svnserve in threaded mode. I believe
I also had success with the tests over http:// with Apache worker but I
can't remember for sure.

No.

Is your repository BDB? If so you could try migrating to FSFS. If you
are using BDB which version is the library?

You could try running svnserve in threaded mode with the svn:// protocol
to see if the problem is limited to Apache.

You could try building more recent APR/Apache/Subversion.
