Why do you think it has enough space? Is it running out of space on
the filesystem where the SVN repository lives? Are there, perhaps,
bulky files or log files that have been deleted but still take up
space on disk? This is a classic problem when allocating space on
"/var" for both Subversion and log files. And one bane of Subversion
is bulky commits of binary files, which do not compress well and are
not easily optimized as a "diff" with a teext fource file.

Is the filesystem on which the Subversion repositories live running
out of inodes? This can be reviewed with the "df" command on Linux or
UNIX systems.

Do you monitor your servers for space use? Good monitoring tools like
Nagios can really be your friend for noticing these issues before they
get out of hand.

What OS are you using for your servers, what version of Subversion,
and how do you have the filesystem laid out? What partition is your
Subversion server on?

We might be able to give good advice, but you'd need to provide a lot
more information.
