["outputs.influxdb"] did not complete within its flush interval

Stats are collected from 6 nodes (in few months + 4 nodes), every 300 sec. Regarding config:

interval = “300s”
metric_batch_size = 11000
metric_buffer_limit = 12000
collection_jitter = “0s”
flush_interval = “22s”
flush_jitter = “0s”

What could be changed to get rid of “did not complete within its flush interval” warning?

Thanks!
