I've opened two support requests with VMware in the last 60-90 days. I've rebuilt my VCSA per their recommendation. I still have the same issue.
I have one VCSA that started to have web client slowdowns after upgrading from 6.7U1 to 6.7U3. I do not have OpenManage installed on the hosts. I've manually verified that OpenManage isn't installed on each host within this vCenter.
Logging into the VCSA via SSO/Active Directory takes a very long time (2-5 mins). Even with workaround https://kb.vmware.com/s/article/53698 applied.
I need to reboot my VCSA every 2-5 days to restore performance.
Once logged into the VCSA it doesn't always behave correctly - sporadically the UI slows down to the point where right clicking to bring up a context menu takes 2-5 minutes. This occurs on any browser even when cache is cleared.
The ESXi hosts are running the latest build of ESXi on Dell PE R740xd's.
Occasionally, rebooting the VCSA will dis-join it from the domain (Windows 2003 functional level). I know this functional level isn't supported and it's been difficult to get an answer as to whether this would cause these issues or not.
Any ideas?
