I have found that Vietnamese has a parsing error in logStash
I want to know how to avoid errors.

This looks like a case of broken XML. Can you share the full XML document?

We parse more than 100 xml files at a time. Then an error occurs and Incorrect data is entered.
Note that we delete files stored in Elastic Search DB after 7 days.

It is difficult to find the cause of the error. There is nothing in common.

and LogStash has a bug that does not work if there are more than 5000 files to process.
so we delete the files stored in Elastic Search DB

Any help appreciated.

1) error

2) incorred data
