"The request failed because the remote server “Vcenter name / ip” took too long to respond. (The command has timed out as the remote server is taking too long to respond) OR "{Connection Time-out while waiting in the queue}"

>how to identify if db for vc is corrupted any symptoms,logs we have to search, where to diagnose if db is corrupted?

> Found Memory was almost consumed  by java.exe and vpxd.exe..is this related to db corruption or any other symptom ?
> cpu was almost 100 % on Vc
> on db all looks fine but free space in db drive was only 1-2 gb ..so that could be reason to corrupt the db ?

If your SQL DB is corrupted, vCenter Service will not start, or will crash, and stop when you access a function within vCenter Server.

Simply re-install vCenter Server, add hosts, and carry on.

Very little impact - remember it's a management and configuration server.

It will also not affect running VMs on Hosts.

Hi

What is the size of your vCenter DB?? Maybe is too big and is full?

You should check vCenter logs first and see if you have any errors
