问题是索引器的批处理大小设置为0.请在门户中编辑索引器的属性，并将批处理大小"设置为某个合理的数字(10是默认设置，但是如果您的文档较小，则***使用100-500之类的文件).

The issue is that your indexer batch size got set to 0. Please edit indexer properties in the portal and set the Batch Size to some reasonable number (10 is the default, but if your documents are small, something like 100-500 may be better).
