Multi-threaded Local Search's ExecutorService didn't terminate within timeout

[Shi Alexander]

Hi there,

When I set a solver config.xml as below:

    <termination>
        <secondsSpentLimit>50</secondsSpentLimit>
    </termination>

    <localSearch>
        <termination>
            <secondsSpentLimit>5</secondsSpentLimit>
        </termination>
        <localSearchType>TABU_SEARCH</localSearchType>
    </localSearch>

An error occurs:  

ThreadUtils.shutdownAwaitOrKill: Multi-threaded Local Search's ExecutorService didn't terminate within timeout (1 seconds).

Is there any ideas to set shutdownAwaitOrKill ?

Thank  you.

Shi,

Might you have a reproducer for this issue?

With kind regards,
