Probably more than a few hundred.  Look for "Argument list too long"
from the following document.

  http://www.gnu.org/software/coreutils/faq/

However I think you are using du incorrectly.  The -X option is
expecting a single argument that is a file containing patterns to
exclude.  You are handing it many because the command line shell will
expand the "file glob" dsp_* into many different arguments.

  -X FILE, --exclude-from=FILE  Exclude files that match any pattern in FILE.

Try this instead:

      --exclude=PATTERN Exclude files that match PATTERN.

  du -s --exclude="userimages/2519/dsp_*"
