I think an old version of BOINC (which was available at that time) had a problem with the host names. What BOINC version are you running?


I got 6.2.12 from "Synaptic-Paketmanager"

Now, about the hostnames issue. I don't think it's the hostname problem, you've probably had copied whole BOINC installation from one host to another. If you do that, you copy over host id and connection counter. When one of your hosts contacts server, connection counter gets increased, however, on other computers having the same host id (because it was copied over), the counter has not been increased, so BOINC sees it as a communication failure and trashes all WUs. The safe way to copy things from one computer to another is to exclude client_state.xml.



I installed BOINC on both hosts with "Synaptic-Paketmanager" without any file-transfer between the hosts.

I found the old BOINC logfiles from December:

stdoutdae(PC1).old.txt (~2MB)

stdoutdae(PC2).old.txt (~2MB)

First PC was attached at 12-Dec-2008 23:24:05 MEZ

Second PC was attached at 13-Dec-2008 18:30:15 MEZ - and got the same "Computer ID: 90641" as the first.

Up to 13-Dec-2008 13:00:00 MEZ never crunched both at the same time for Primegrid - no problems

But at 13-Dec-2008 13:00:00 MEZ the Race - and the "Dance" starts.
