Message 5542 - Posted: 23 Oct 2016, 10:15:19 UTC

hello
At my last calculation it stopped at 99,97 because not enough memory. I Checked only 2 Go of 5 Go reserved for this task was used. It's not the first time that the system stop the calculation and after few days the delay to send is over.

Any idea why ?

Well , it's not always easy to say why .Above all, even with good parameters , a bad Work Unit can occur without solution.But if it arrives too often , then, there 's perhaps something to do.

Let's try:

1°) Are only the 4 cores WU concerned ?
2°) How many WU do you run simultaneously?
3°) What is in your app_config.xml?

In the log of the rebel WU, we can watch the statement of the task running :

Stderr output

<core_client_version>7.6.22</core_client_version>

BOINC will be notified that it needs to clean up the environment.
This is a temporary problem and so this job will be rescheduled for another time.
