Hello

I recently upgraded to filebeat v5 (and the rest of the ELK components). However, I am now seeing the following error on filebeat when shipping the logs across:

2016-12-05T10:42:05Z ERR Failed to publish events caused by: read tcp 172.30.168.235:60542-\>172.30.168.244:5044: i/o timeout

Anyone else see this before?

Thanks!

@jinal.shah Have a look at the search results here: [https://discuss.elastic.co/search?q=ERR%20Failed%20to%20publish%20events%20caused%20by%3A%20read%20tcp](https://discuss.elastic.co/search?q=ERR%20Failed%20to%20publish%20events%20caused%20by%3A%20read%20tcp) Several solutions have been discussed in the past.

Thanks @ruflin - Added bulk\_max\_size: 1024

That fixed the issue for me 🙂
