We are getting "Concurrent Requests Limit Exceeded." in our production org . Some transactions in our ORG require to much time as they involve callouts to external systems. Thus taking more than 5 seconds in execution and leading into concurrency.
Is there a way in which we can find number of processes in execution that have taken more than 5 seconds(i.e they are currently running and taking lot of time) so we can postpone newly created transactions for some time thus avoiding hitting concurrency request limits.
