Subversion fail on move a file

I have a subversion repository, and when I move a file, it report the next error:

svn mv file开发者_开发知识库1 file2
svn ci -m "Message"

svn: Commit failed (details follow):
svn: Server sent unexpected return value (200 OK) in response to COPY request for '/svn/practicas/software/!svn/bc/78/file1'

I don't know what is the problem. Can help me anybody?

Does your server has some free disk space where it stores the SVN revisions?
