Is migration is going on in cluster?
Recommending you to use latest aerospike tools. [Aerospike Downloads | Aerospike](http://www.aerospike.com/download/tools/3.7.3/)

Looks like you have lots of scan job running in background. Asbackup issues a new scan for which its seeing max running job reached. Can you provide information about how many scan jobs running?
Run following command using aql: aql\> show scans

Thats why you are seeing scan jobs for asbackup is rejected. Wait for those scan jobs to complete, or if you dont need them anymore kill them .
Issue following command for the same:
Kill one scan job :- asinfo -v ‘scan-abort:id=jobid’
Kill all scan job :- asinfo -v ‘scan-abort-all:’

is it because that i have killed a asbackup progress that caused this problem?

Maximum scan job active in a system is configured to 100. So Apart from killing one asbackup there is something else which stopped many scans, or may be during long period of time it happens.

This _is_ configurable. See the configuration parameters [`scan-max-active`](http://www.aerospike.com/docs/reference/configuration/#scan-max-active). You should also check that your [`scan-thread`](http://www.aerospike.com/docs/reference/configuration/#scan-thread) value is set correctly. It should be equal to the number of cores on your machine.

i think i knew where the problem is , i wrote a shell script to backup everyday ,but with large amount of data , it cannot be finished in one day then another process of that shell runs , so it may cause too many scan operations
