I don't know how I missed the updates to this - probably because they came on the weekend when I'm not looking or something....
So a few comments after the fact for those scrolling through the thread:
First, I HIGHLY recomment the courses listed above. I have taken a number of them, including the Backups course and the DLS course, and in addition to that have taken the whole recommended North American training track as of a couple of years ago. I will add that the Backups course is written in a VERY broad scope, and begins with an introduction of all the different operating hardware used in the 4K - I believe all the way back to V4 - it clearly explains how it works and how the components interact with each other, and then continues on to explain how, as each new release of the hardware came out, it differs from the previous, AND it gives you the similarities between how the old hardware used to work and how it works now in the new hardware. This is especially important because in 4K V6 they switched to Linux, and as they moved forward they took the functions of whole separate processors and Virtualized them together - so you have the Linux at the bottom of the pyramid as the "platform" that ties the hardware to the software, and then adds layers on top of that until you get to the 4 Virtual Machines that are actually handling all the traditional telephony and communications tasks. It will help you understand that Assistant is one of those 4 VMs and it can be started and stopped without taking down the whole system, and that Configuration is a "program" that runs on the "Assistant VM" along with many other "programs"... Anyway - that's my plug for those classes. When you take the class you get the class, and a downloadable copy of all the physical training materials from the course for future reference.
Secondly, whenever you have an Assistant / Config Manager problem I recommend the following order of operations:
If you get UPLOAD REQUIRED anywhere, as stated above, go into Config Manager - Network - System, then click the Search button. Then click Action from the menu above and hit Upload All. That will take a bit of time and I don't recommend doing it when the system is under high load. After that everything should say SYNCHRONIZED.
IF not:
First, use Webmin to Reboot the Assistant
If that fails then restart the Configuration Manager using the above process.
That will usually resolve the issue.
As a matter of fact, one of my techs often refers to "giving the system an enema" on occasion, and I would recommend that you periodically DO restart the configuration manager. That will allow it to clear all its caches and work areas and when it starts back up you will find it to be much more sporty and speedy - until it gets bound up again and slows back down...
I DO NOT suggest touching the "Assistant Reinstallation" function in the portal unless something really bad is going on. That is kind of Akin to reloading windows over the top of windows, and you really don't want to do it unless support tells you to, or if you have been doing this a while and KNOW that's the only solution.
