我有以下问题： 昨天，由于未知错误，复制在我的主服务器的3个从属服务器上停止了工作。我在两个从属服务器10.3和另一个10.2的主服务器上都有mariadb 10.2。该错误的描述如下面的日志所示。在位置“ 261112394”的日志“ miservidor-principal-bin.005515”中，复制停止了数小时，直到此刻在没有使用mariadb 10.3的服务器中进行任何干预的情况下，进行了更改并在日志中注册：重新连接重试，日志“ miservidor” -principal-bin.005516”位于位置11324538，具有10.2的服务器仍被删除，而具有10.3的服务器则通过任意设置新位置而得以恢复。有什么解释吗？我不知道这里发生了什么。进行更改时会丢失数据吗？是正常的吗？
