The brief description is that I have one host (Rod-i5) that appears twice in the Host list screen. One instance shows the credit being earned, the other instance is the one whose setting affect the host! The second one is also the one that shows updated "last contacted BAM!" dates.

The long description:
On 27 June 2016 I had a couple of power failures which caused corruption of my Boinc installation. When I opened Boinc there were no projects. Looking at the Boinc data folder it looked just like a clean install. I suspected that Boinc 'cleaned' itself after the corruption - don't know if that's what it would actually do. I added BAM as my account manager, hoping it would connect as the same PC. Unfortunately a new host was created with a new BAM! ID, which I had to configure by selecting the projects in BAM.

I noticed that the old host (Lets call it A), was still showing updated credit stats, while B was not being updated, and shows "Host ID doesn't exist in BOINC combined or doesn't have any credit" if I try to view its stats. I thought this was a case of split ID. Since I was going away for 9 days I left my hosts crunching, hoping that the ID would sync up. Returning from my trip things hadn't changed. On 12 July I uninstalled and installed a freshly downloaded version 7.6.22. The version I had been running was 7.6.9. After the uninstall I checked the data folder and found the projects folders were not removed by uninstalling. In the interests of completeness I deleted all Boinc related folders before installing.

When I connected to BAM it connected as B - it didn't create a new host this time.

I'm hoping that I can get this sorted out, as host A will time-out because it doesn't update "Last contacted BAM!" and I will no longer be able to monitor its credits, although I will be able to change settings by using host B!

I have checked all projects that the PC is attached to, in case a merge was necessary, but all of them only show one version of the PC.

Any ideas? (If you read this far!)
Is there something you can/need to do, Willy?

Thanks and regards

Replying to my own question I found the answer so it may be useful to someone.

After a month the old host stopped being shown on the hosts screen (this is normal, as I have seen this before). I decided to delete it and bingo! my new host suddenly started showing stats for the PC. Wish I had tried that in the beginning!

How does one fix this problem? I had a client_state error on one computer that caused it to generate a new CPID for Einstein. This generated a new host ID. I merged the old host ID into the new ID (only goes that direction it seems) and now I have two host ID's for the same computer in my Hosts List.

Host ID's

The duplicate is the AMD FX-8370. At least the newest Host ID is generating credit correctly. But it looks like it "orphaned" about 13 million credits on the old Host ID. How does one get that credit back and remove the old Host ID?
