All my workers - that are all there are right now! - are configured as 
follows:
swkj01, swkj02, swkj03, swkj05, swkj06
2 CPU
8 GB RAM
16 GB HDD
2 worker processes in one 8GB RAM disk

and swkj04 and swkj07
4 CPU
16GB RAM
16GB HDD
4 worker processes in one 16GB RAM disk

It is possible, that the RAM disk runs full and then the worker dies, as there 
is no more RAM. Happens, but the packets get assigned to 04 or 07 eventually 
and build through.

I do have a number of older DELL PE 1950 for my experiments, I have equipped 
them with RAM over time. The disk storage is a written off IDE RAID box with 
16 250GB PATA disks in a 12 disk RAID 10, behind 2 PE 1850s as HA NFS server. 
As there is disk space, it is not that fast, it host other machines of mine 
also. So there is no I/O left for workers.


Probably now there are no free workers with approx 3000 packages waiting to 
build, and home projects are dispatched with a lower priority than the main 
repos.

Just wait until the build load reduces.

Greetings,

Stefan
