When the vCenter Server database if full:
- You cannot log in to vCenter Server
- VMware VirtualCenter Server service may start and stop immediately.
To resolve this issue, we need to manually purge or truncate the vCenter Server database. The script to truncate the database is available at the Resolution of the KB Article 1025914 in the “Truncate the event and tasks table” section. For additional information, see VMware Knowledge Base article 1025914 at the following URL https://kb.vmware.com/kb/1025914
