Re: Help! Urgent problem.

HI Ryan, thanks for your help. I have found more information.

Apparently my IT admins have two different version of SVN installed. The
svn/apache/apr installation uses APR 0.9.12. But another svn/apr
installation exists that uses APR 0.9.4. The hook scripts use the binaries
from this installation. This is the source of the hook scripts' inability
to access the repository after a 2+ GB revision was committed.

Anyway, can I tell my IT to upgrade that second svn install to APR 0.9.12 or
is 1.2 really required? It seems like 0.9.12 is working okay. If I need
them to upgrade to APR 1.2 it is a much bigger deal since this affects the
whole LAMPP stack.

To ward off the comment that I know will be coming: Yes, I know you can't
mix APR versions. SVN and Apache are both using APR 0.9.12. It is just
that there is a second SVN install (no Apache) that uses APR 0.9.4.

thanks,
David
