Upgraded 2 machines to 6.10.36 on March 7 and their credits were split into 2 hosts on the stats sites the following day. The ''new'' host has the credits from projects I have contacted since upgrading. I upgraded my remaining 5 machines yesterday so I expect 5 new hosts today! What could cause this?
My hosts

Did the new (upgraded) installation find your old BOINC Data folder, and carry on crunching the tasks/projects you had on board before the upgrade?

If you were asked to re-attach anywhere, BOINC will have created a new Host ID, which would have the effect you describe.

The most common reason for losing the old BOINC data folder, from what I've read, is installing a 32-bit version of BOINC when you were previously running a 64-bit version, or vice-versa. I believe the detection code on the download page of this website doesn't detect the 32/64 bit OS properly with all browsers.

I've upgraded three machines to pretty much every version ob BOINC released recently, including v6.10.36, and never had the stats split. But I'm 32-bit only.

I believe the detection code on the download page of this website doesn't detect the 32/64 bit OS properly with all browsers.

Blame Firefox. IE will send the WOW64 bit when run on a 64-bit OS.

Installation went as smoothly as always. No problems. Carried on crunching. Only have 32-bit. Have looked at others host stats too and see the same thing. On all O/S's. Different days too so I thought it wasn't a stat site problem?
See here and here. Take a look through a projects top hosts and you'll find loads.

EDIT:- now I have 30 hosts! The 5 I mentioned all have ''new'' hosts.

Could the installer be the culprit somehow? I upgraded all my machines from 6.10.18 by uninstalling BOINC first (as usual). Should I have just over-written instead,seeing as they are in the same series? The new install found the old data folder though so I don't understand why it would think it was a new host. I really have no idea!!

I really have no idea!!

Nor do I, which is why I haven't posted it.

Some poking around in the archived logs (stdoutdae.txt, or even stdoutdae.old, in that data directory) would seem to be in order. See if you can find the bit that corresponds to the first re-start after the new version was installed.

The stdoutdae.txt says exiting BOINC requested by user, then a couple minutes later starting 6.10.36. The wording being the same as in the BM. I even got the version change 6.10.18 -> 6.10.36 bit!

What about the "URL: http://***********; Computer ID: 3282456;" bit (before and after the upgrade)? :-)

Can you trace back which project gave out a new host-CPID?

Computer sind nicht alles im Leben. (Kleiner Scherz)

All hosts still have same ID's. I don't have duplicate hosts at the projects only on the stats sites. Bit perplexing!

EDIT:- the only differences I can see now is that the processor description has ''x86'' before the Family type part and the processor features list is longer!

Hi there,

I've exact the same effect, also after I'm upgrade to 6.10.37 the both upgraded host have 2 and more entry in the host list. The other hosts which run 6.10.18 and older Version didn't show that effect.

I did also merge the hosts on theprject sie, but that didn't help long.

6.10.36 and 6.10.37 have been retracted. Do not use them. Do not use 6.10.38 either.
