We have an issue with analytics displaying incorrect data for concurrent requests (especially when viewing the current hour). However, in the database I can see that the limit was exceeded, which is why you were seeing those errors.
The limit is fixed at that value for all applications — as far as I know, there’s no option to increase it for a specific app, but I’ll double-check and will let you know if I find out otherwise.
I’d also like to note that in the vast majority of cases, your app reaches this limit when there are some temporary server-side issues reducing request processing speed, causing unprocessed requests to accumulate until the limit is reached.
We’ll review our side as well, particularly around request duration and any retry behavior that might be contributing to the buildup. Please do let us know if there’s any update on the possibility of increasing the limit.
