Question

我使用ruby驱动程序从mongodb找到文档，将它们收集到数组并迭代它们以更新与下面代码中相同的文档：

crawlarray = @@mongoclient[:crawlarray].find({searchresults:[]},:timeout => false).limit(500)
crawlarray.each do |elm|
    finalsearchstring = elm['searchstring'] 
    if elm["searchresults"].blank?
        ap "SEARCHING: #{finalsearchstring}"
        results = searchG(finalsearchstring) 
        elm["searchresults"] = results
        @@mongoclient[:crawlarray].update_one({"_id" => elm['_id']}, elm)
    else
        ap "ALREADY SEARCHED: #{finalsearchstring}"
    end
end

有90K的记录，但正如你所看到的，我只得到500就不会得到错误。每次，经过大约150次迭代后我得到这个错误;

有人可以帮我解决一下吗？
