Hi,
It seems indeed caused by a kernel version upgrade, since I did the test of booting the OS with Linux 4.7, and everything is fine (i.e. the client processing tasks normally). I'll ask the WCG project guys.
Thanks a lot for you help!

Hi,
I am using boinc-client 7.6.33 x86_64-pc-linux-gnu on a Debian linux system.
Projects: World Community Grid
Since a couple of days, the client has stopped processing tasks, and I can't find out why.
The 'Projects' tab shows a status with 'Communication deferred' with a countdown. The 'Tasks' tab does not show active tasks, the only I see have a 'Progress' to 100% and a 'Status' of 'Computation error'.

The event log says: 
Computation for task <task_name> finished
Output file <file_name> for task <task_name> absent


I have also looked in the working directory and the file 'client_state.xml' has some 'result' nodes showing errors, for example:
<result>
    <name>MCM1_0129167_4365_0</name>
    <final_cpu_time>0.000000</final_cpu_time>
    <final_elapsed_time>0.000000</final_elapsed_time>
    <exit_status>11</exit_status>
    <state>3</state>
    <platform>x86_64-pc-linux-gnu</platform>
    <version_num>736</version_num>
<stderr_out>
<![CDATA[

        <open_name>result.out</open_name>
    </file_ref>
</result>


Do you have any ideas of what happened and how to get the boinc client running again ?
Thanks and best regards,
Dimitri
