ONTAP API Concurrent Connection Limit

enyang — Wed, 04 Jun 2025 19:41:37 GMT

My clients found his scripts were getting stuck while a great deal of commands were being dispatched, which causes the following api call queued up.

May I know is there a ONTAP API concurrent connection limit? and is it a tunable value?

Thanks.

Hello @enyang,

There are no published limits that I'm aware of, but it is important to remember that ZAPI is a service running on the controller, and like any other service, it has a finite number of resources. I don't know what scale your customer is dealing with, but it may be prudent to have some throttling on the client side.

Please reach out to me internally and I can provide a bit more info.

I've seen similar issues myself - could you explain if the zapiretrycount switch would help in these scenarios or will it just compound the problem?
