Symptoms
Cause
Too many /api/types requests from multiple Virtual Machines cause this issue.
Resolution
The Unity Administrator must investigate which Hosts are overflooding the Unity Array with these requests.
As a temporary solution, Management Service can be restarted, as per
Article Number 000490488 .
However, for a permanent resolution, Hosts and their respective Virtual Machines must be halted and investigated, as these are the cause of the issue.
For further assistance or clarification on this issue, please contact Support and refer
Article Number 000541664 .
This behavior can be confirmed by looking up the amount of /api/types request being logged at the access_log.
It can be verified with the below command:
service@spa:~/user# grep -i "GET /api/types" /nas/http/logs/access_log | wc -l
To identify which Hosts are responsible for these requests you may use the command below:
service@spa:~/user# cat /nas/http/logs/access_log | grep -i "/api/types/loginSessionInfo"10.60.15.70 - - [19/Mar/2020 06:45:42.597172] 2548 [19/Mar/2020 06:45:42.599720] "GET /api/types/loginSessionInfo/instances HTTP/1.1" 302 294 "-" "-" "-"
As we can see at the example above, Host holding IP Address 10.60.15.70 is one of the many causing the issue.
