Cisco module, ES error too many dynamic script compilations within, max

I had Cisco ASA logs coming in fine awhile ago (7.4.0). Then they just stopped, no parsing happens, and this error is everywhere:

[script] Too many dynamic script compilations within, max: [75/5m]; please use indexed, or scripts with parameters instead; this limit can be changed by the [script.max_compilations_rate] setting

I'm testing out an ELK cluster, all on 7.4.1 now, for beats also. Not sure what is up, I don't see anything in the debug log on the filebeat box itself.

Hi @JSkier,

can you set script.max_compilations_per_minute at elasticsearch to a value that might fit your needs (you will need to test, but sounds like some 20 should be an starting point)?

Thank you, I tried this:

PUT /_cluster/settings
{
    "transient" : {
        "script.max_compilations_per_minute" : 20
    }
}

And get this error:

>     "type": "illegal_argument_exception",
>     "reason": "transient setting [script.max_compilations_per_minute], not recognized"
>   },
>   "status": 400

I also tried sending a persistent command. Should I be setting this on each config file of every indexer? Doesn't seem to like the cluster setting.
