VMware Cloud Foundation: SDDC Manager Backups continually failed with "OSError: [Errno 24] Too many open files"

Products

• VMware Cloud Foundation

Issue/Introduction

Symptoms:

SDDC Manager Backup fails with the error: "Too many open files".

Environment

VMware Cloud Foundation 4.4.1
Vmware Cloud Foundation 4.5.1

Cause

Every SDDC Manager backup operation was leaving a few open file handles and after a few months the file system was full due to those open file handles. This issue is noticed when the SDDC Manager backups are scheduled with an hourly frequency.

Resolution

This issue has been resolved in VCF 4.5.1 and above releases.

Workaround:

To workaround the issue, restart the 'sosrest' service.

1. SSH into SDDC-Manager as a root user.
2. Run "systemctl restart sosrest".
