Exhausted Semaphores- Error 429

[poonam_modi]

Hi,

We have our SNOW instance integrated with AWS. When we receive a payload from AWS, using Scripted Rest API,we receive it in SNOW and transform it to our available table. Recently, we received the error 429(exhausted semaphores for API_INT ) causing teh integration to break. Automatically after 8 hours approximately, the semaphores were available without any changes made from our end/vendor end. The number of transactions coming from AWS were similar.

Could you please share your inputs regarding the same.

Thanks

Hi - can you check if your instance patch or upgrade happened during the time of this failed import? This could be one of the possibility of resource contention/timeouts.

Thanks Balajii. There were no patching/upgrades performed.
