Strange.
And now I'm confused. It looks for me as something (the einstein database?) mixed some host IDs ...
Does someone have an idea what happend?
Thanks
I'm confused ...

OK, couple of things.
First off, when you are looking for specific tasks in the CC logs, you have to search for the filename of the task to see if there are any entries for the candidate tasks you are interested in.
If there aren't any at all, then that task is most likely a ghost.
The strange part here is that ordinarily EAH is configured to resend 'lost' work to the host if possible and necessary. Therefore, if the 'red' tasks were in fact ghosts, why didn't the project resend them before they expired on deadline? It's had plenty of opportunities to do so since May 12th (that's the first showing contact time after the send date of the expired tasks).
The next question is, did you detach the project? If not, then this looks like a spontaneous detach.
The only thing I know of which causes one of those is if the CC sends a scheduler request to the project which is less than or equal to the last RPC Sequence Number the project has on record as coming from the host. Typically, that comes from things like trying to restore the BOINC folders from a backup set, a really ugly CC crash which requires it to rollback to the backup client_state file upon restart of the CC, and/or a user error in editing the client_state.
HTH,
Alinator
You can also get detaches
)
You can also get detaches from account managers if the project is not properly listed in the AM. I have had BAM do that to me a couple of times ...
RE: You can also get
)
Hmmm...
Don't know, never used an AM.
However looking this over again, that might be a good candidate cause here if the OP uses an AM.
Alinator
RE: RE: You can also get

Just a thought. I usuallly use them only when setting up a new computer to save typing. Connect to the AM and it downloads all the 50 some projects to attach ... saves looking up URLs and passwords.
Then I detach...
RE: OK, couple of
)
This computer has not been detached from the project, it still receives workunits. And I never used an account manager. I also have not seen any "strange" workunit entries in the boincmgr view, all workunit shown there were finished fine. so I assume my computer has never seen these workunits ... and why should it, the computer requested no work or received work at this time.
ntp is set up and in sync, the timezone ist 1 hour different and the log ist complete for the may 10th.
And no entries in the log for "lost results".
The funny thing is:
10-May-2009 15:11:44 [Einstein@Home] Sending scheduler request: To fetch work. Requesting 40513 seconds of work, reporting 0 completed tasks
10-May-2009 15:11:55 [Einstein@Home] Scheduler request succeeded: got 2 new tasks
And my computer received two workunit ... and not the red workunits.
...
And much more strange: see http://einsteinathome.org/host/1938556/tasks
The website says, my computer is detached ... but that's absolutely wrong. http://einsteinathome.org/host/1938556 is my computer ... and the boincmgr shows 3 active workunits.
Slowly it's getting weird.

Strange indeed, I forwarded

Strange indeed, I forwarded this to the admins.
One question: The logs mentions somethings about a changed venue (which probably prompted the generation of a new CPID). Anyway, did you change the venue or something else on the morning of May 25?
Do you still have the logs available for 25 May 2009 11:50:38 UTC the time when the client detach was received by the server (and a few minutes before that time)? That might be helpful when trying to nail down the problem.
Thanks

RE: Strange indeed, I

I did not change anything, not even the venue (at least I do not know). Additionally, I'm using an global_prefs_override.xml file which was unchanged ...
I have any logs you or Bernd or any admin likes to have back to Feb 2009. The actual log is around 250k and can be mailed.

This is really
)
This is really puzzling.
Just a wild shot in the dark: Around the time where the problem started, you attached a new host : http://einsteinathome.org/host/1955506
Is it possible that somehow (e.g. by initially cloning the BOINC directory) the new host assumed the identity of the other hosts and threw the client-server comms out of sync? It seems to be quite a coincidence that the problem started very shortly after the new host was attached.
