The libpng project has 777 releases on a single series. This is caused by the Release URL Pattern on the "main" series which automatically downloads new versions of libpng tarballs and creates a revision to hold the file.

Even projects that don't have that many milestones or releases may have problems displaying all of them since each milestone will display stats on how many bugs and blueprints are assigned to it.
