Seeing "app instance exceeded log rate limit (16384 bytes/sec)" error for a task/job.
The error is seen because the default log rate limit (per second) is being used when the job/task is running.
If the developer believes the default log rate limit (per second) is not sufficient for some specific job/task, then there is option to set another value either from Apps Manager UI or CF CLI.
Apps Manager UI
CF CLI:
$ cf create-job my-app my-job "pwd"
--disk LIMIT or -k LIMIT sets the task disk limit.--memory LIMIT or -m LIMIT sets the task memory limit.--logs LIMIT or -l LIMIT sets the task log rate limit.
* --logs -1 can be used for log rate to specify an unlimited log rate task.
