Cause
The issue occurs when the number of open files allowed for cloud user or number of processes allowed for root user exceeds the default limits.
Resolution
To resolve the issue:
- Login as root user to the machine running the cloud-usage service and add the following lines to /etc/security/limits.conf file:
cloud hard nofile 8192
cloud soft nofile 4096
root soft nproc -1
root hard nproc -1 - Logout as root user and login another time.
Note: This step is required to reflect the changes made (for root user) in the limits.conf file.
