Sitecore 日志文件重复错误

Question

我有一个 sitecore 7.2 站点，它是从 6.6 升级而来的，任何导致以下错误在日志文件中多次出现的想法:

ManagedPoolThread #3 2015:07:14 10:03:48 ERROR Exception occurred in retryer scope :

您多次看到相同错误的原因是因为重试器将重试失败的数据库请求的次数等于尝试次数参数中设置的次数。

下面是取自 web.config v7.2 的重试器部分:

<!-- RETRYER
         When enabled, the Retryer resends failed database requests a specified number of times.
         For example, this is useful if you configure a Sitecore instance to support hot failover for database calls.
         Default value: disabled="true"
    -->
    <retryer disabled="true" type="Sitecore.Data.DataProviders.Retryer, Sitecore.Kernel">
      <param desc="Number of tries">6</param>
      <param desc="Interval between tries">00:00:00.500</param>
      <param desc="Log each exception (should be used for debug only)">true</param>
    </retryer>
