@thinhluu can we get a bit of details about the environment?

Logstash version? S3 input version (You can get that by running this command bin/plugin --verbose input-s3) The size of the AWSLogs/AWSAccountID/CloudTrail/us-west-2/2016/02/26/AWSAccountID_CloudTrail_us-west-2_20160226T0800Z_g8AAxJTg73yheICE.json.gz Number of files in the bucket?

ph commented 8 years ago

Not sure if the download timeout and the exception is not correctly raised?

Is the machine processing the logs is also on AWS?
