Today, when I came into my office, 10 from 12 BOINC-Clients have crashed.

Looking in stdoutdae.txt shows:

22-Jun-2010 02:12:00 [---] Account manager contact succeeded

On 02:12:00 the client crashed

I checked a second client and it seems to be exactly the same: The last line is "Account manager contact succeeded" and then the client crashed

Oh, I forgot: The first mentioned client had already crashed soem hours before; same point "Account manager contact succeeded" is last line in stdoutdae.txt

Oh2, the clients vary from older versions up to the latest ones, so it is definitly not a client specific problem

Yeti

Can't reproduce. All my clients have the same messages and they didn't crash.

It seems as if it has to do with the url-change of freehal:

2-Jun-2010 10:48:06 [---] Account manager: Delayed detach from FreeHAL, project changed URL.
After detaching project will reattach with new URL on next RPC!
22-Jun-2010 10:48:06 [---] Account manager contact succeeded

After this contact, the client crashes immediatly

I can reproduce this as often as you like

Meanwhile the client is attached twice to freehal ...

22/06/2010 11:02:16 FreeHAL@home Detaching from project

After this, one Freehal is still remaining, but I can not detach, because the detach-button is grey

With the next contact to BAM, the client crashed

During BAM-communication the client tells that an error occured while communicating with BAM

To get my client working again I finally:

1) detached from BAM
2) detached from FreeHal (1st)
3) detached from FreeHal (2nd)
4) reattached to BAM

Now, it seems that the client is working again. Several BAM-contacts have followed but no chrash has happened again

So, I will have to do this with every client on my network :-(

If you want me to reproduce it or help to test if you could solve this problem, I have 1 client staying in last configuration so that we could use it to test ...

Please let me know if I should keep it as it is or fix it manually as my other clients

...same crashes here with boinc 6.10.56-final

I have removed freehal from my project list in BAM but this project is ever listed. Now i could reattach to freehal in BAM but with a listed freehal i got and will get the known message:

I just upgraded to BOINC 6.10.56 and my client also crashed after every BAM! connection. I downgraded to my previous BOINC version and the problem is gone. I suspect a bug in the BOINC code.

Edit: reported it to the BOINC devs.

Thanks, i was to slow...

I have the same problem here with BOINC 6.10.18.

After detaching with BAM!,see here:

FreeHal is still listing in my BOINC manager???

This is what I do not understand,"After detaching project will reattach with new URL on next RPC!"
Why reattaching?
I want to detach from FreeHal.
The checkbox in BAM! is empty.

HM, it has happened to a lot of different clients:

5.10.28
6.10.13
6.10.16
6.10.36
6.10.51
6.10.56

Yeti

edit: filling in Version 6.10.13

LostBoy, try the "Yeti" way.

Past detaching from FreeHAL, reattach to BAM and some BAM connections i want to be stupid. I reattached to FreeHAL again and had the same situation like before. The boinc-client is crashing in the next connection to BAM and FreeHAL is listed twice in boincmanager.
Here is a snipped from my client_state.xml:


I have done the Yeti way again and reconnected to BAM without FreeHAL on all hosts.

Same problem here as well. Each time the client tried to sync with BAM, it crashed immediately.
The only way to fix it was to delete the freehal accout xml in the boinc data directory and disabling Freehal in BAM as well.

It was a combined problem of BAM! and the BOINC manager. The problem has been fixed at both sides (immediately in BAM! and in the next BOINC version) and the problem should no longer occur.
