I am not really sure, how the contraints management in OBS is working 
(regarding the workers). As usual the documentation is sparse at best. I 
do not know how the dispatcher gets to know of the capabilities of 
workers, and if this is a feature in newer versions of the workers only.

My workers "should" provide the necessary resources, at least swkj04 and 
swkj07, the workers run in chroot mode and have thus, at least 
potentially, access to the whole system resources, as long as the other 
processed do not fill up their (RAM)disks to the max.
They are the old ones, but in my understanding the worker code is 
downloaded from the server installation, so they should be new enough. 
If someone does indeed know more about the constraints feature of the 
build process, please help!

In the past - before the crash and before I added my workers, there were 
at least three more workers provided by [not me], which are now "lost in 
time and space" - meaning, I do not know who ran them and how to contact 
them. These machines obviously had no problem compiling resource-hungry 

Having said all this, I welcome any offers to supply workers. If you, or 
anybody else, are/is able to host a worker, I am happy to help with the 
setup and of course provide the needed obs and openVPN configuration.
