The project the client is currently attaching to is "upper", however from the log it is also observed that it picks up older projects namely "mci" and "uc" while processing. Not sure why this is happening.

You have a funky setup. The IP you see in the scheduler.log is that from the client. So it seems your client has several IP's. Could you also please use a standard BOINC Client and not a self compiled one. It seems you have an older
version of the source code so please update the client to 7.2.28 (official download) and try again. To see what projects the Client is actually attached to you can use the BOINC Manager GUI that can also control remote instances of the Client.

You should also set a sched_debug_level of 3 to get the debug output in scheduler.log

Regards
Christian

And added to what Christian said, could you also tell us what name you gave to your science application(s)?

I installed a new client (this time on a windows 7 box). Previously it was a self-compiled client on a ubuntu box.
I still get the same error - 0 tasks found.

The reason why no task was send can only be found in the scheduler.log and only if you have increased the loglevel and restarted the project.

Are you sure there are tasks available? On the server you also have the tool "./bin/show_shmem" to see what the scheduler knows about.

P.S.: I whoised the Server-IP in the log. Is this an in house project for the company that owns this subnet?

The debug level has been set to 3 (right from the beginning).
And this is the only information I have from scheduler.log:

I have no further idea. I will contact the main developer and ask if he knows another way to debug work send.

Thanks. Let me know if there are any additional inputs from the main developer.

I played a little bit with my test server. Even with debug level=3 there isn't much debugging information written to the log.

You really need <debug_send> and maybe <debug_version_select> and <debug_quota> too to get anything useful information.

i have the same problem , i get no tasks :) but work units are there and jobs files are created i don't know whats the problem :(( i and have the same output as shruti

I recently also had the problem with unsend tasks and solved it by enabling the <debug_array/> logging for the scheduler. For everyone who also suffers this problem please enable the following options in your config.xml:

<debug_send/>
<debug_version_select/>
<debug_array/>
<sched_debug_level> 3 </sched_debug_level>

Than restart the project (bin/stop; bin/start), update the client and post the part of the scheduler.log that corresponds to this RPC. Best way I found is to use grep as follows:

cat scheduler.log | grep HOST#2354

This will give you the latest RPC of this host (change to suit your host) extract the PID and run another grep:

cat scheduler.log | grep PID=26407

This will give you the whole request and messages.
