fluentd: td-agent sends logs with hours delayed and keeps warning about slow flush

We’re running td-agent 3 on Ubuntu 14.04, EC2 instance m4.2xlarge

$ td-agent --version
td-agent 1.2.2

$ dpkg -l | grep td-agent
ii  td-agent                                 3.2.0-0                                    amd64        Treasure Agent: A data collector for Treasure Data

Configurations Logs from server nodes are forwarded to a log-aggregator before sending to ES.

Here’s the piece of conf on server node

the logs directory has quite high volume of logs, started out like this, and could grow drastically, logs generated continuously.

td-agent started working properly, following tails of *.log files, and sending logs in almost realtime, just after a while (several hours), it started sending logs late by half an hour and more, then almost not sending anymore, or too slow, we see lots of warning about slow buffer flush

which made it almost not working as expected.

This seems happen only on this server, on some other servers (which might have lower volume of logs) it seems working normally.

Is this a problem of performance, the server is quite strong and we’ve tried tune td-agent flush with flush_thread_count but the issue still happens, like just a matter of time?

Update: We also saw lots of chunk bytes limit exceeds for an emitted event stream warnings on the log-aggregator server, not sure if it’s related
