When trying to edit a large Watchlist on Commons (> 40.000 pages watched) editors cannot edit this watchlist, but get a generic Wikimedia Foundation error warning "our servers are experiencing a technical problem.. please try again in a few minutes"). Trying again never helps, this is a constant problem for months now.
Known long-standing issue :/ *** This bug has been marked as a duplicate of bug 39510 ***
