System info

Telegraf 1.32.0 (replicated in windows and kubernetes)

Docker

No response

Steps to reproduce

Run two different InfluxDB instances
Run Telegraf with the provided configuration: buffer_strategy = "disk", two InfluxDB output plugin configured, one input to collect metrics and one internal input plugin to collect internal metrics.
Wait some seconds for the error (the flush interval configured?)

Expected behavior

Telegraf writes metrics to the configured InfluxDBs without crashes.

Actual behavior

Telegraf stops working. Telegraf uses a folder with the plugin name to write the buffer data to the disk. If the output plugins are of the same type the concurrent go routines maybe are trying to read/write the same data file inside this folder. Maybe by using the alias as folder name could solve the issue.
