[Dxspider-support] Nodes running in Cloud VMs (was EXPORT_USERS fill the entire disk)

[Dirk Koopman]

I have consulted someone that has a lot more experience at the sharp end 
of cloud than me and one of the things he suggested is to disable any 
NTP server you might be running in your VM image. The base/host machine 
will already be using NTP and, likely, it will disagree with the your 
NTP (configs will be different) and will thus cause a serious amount of 
time jitter, If you don't run NTP in your VM, then the image should just 
use the base machine clock. This *might* help as DBD is notoriously 
fickle about all sorts of things that it really shouldn't be concerned 
with or should handle properly itself, rather relying on the programmer 
to cope with things like explicitly closing the database.
