Active tasks are not canceled immediately

When you select multiple tasks on the Active Tasks page of the Operations Center and attempt to cancel them, the tasks are not canceled immediately. There is a longer delay for spoke-server tasks than there is for hub-server tasks.

Symptom

Table 1 shows sample data from one test environment when an administrator canceled multiple tasks. These results might differ from the results in your storage environment.

Table 1. Approximate delay times when tasks were canceled in a controlled environment
Number of tasks canceled	Delay for hub-server tasks	Delay for spoke-server tasks
1	5 seconds	5 seconds
10	5 seconds	7 seconds
100	10 seconds	25 seconds
1000	40 seconds	3.5 minutes

For example, when the administrator selected 1000 hub-server tasks and clicked Cancel, it took approximately 40 seconds for the tasks to be canceled.

Solution

Wait until the tasks are canceled, or cancel fewer tasks at a time.
