Hi there,

I ELK version is 5.6, and logstash received the log.From log, it complains ""undefined method `sanitized' "

Every time, it's normal when it's just started. Slowly, this error will occur frequently in the log; suddenly one day, I found that the index data is not updated, and there are many such errors in checking the log. At this point, I need to restart to restore normal.

Please help.

Thanks and Regards,  
yun
