You should look into configuring more Qv Engines available for distribution. Pick the minimun value between your server cores and 9.

QMC -> System -> Distribution Services -> QDS -> Advanced -> Max number of simultaneous QlikView engines for distribution

QMC -> System -> Distribution Services -> QDS -> Advanced -> Max number of simultaneous QlikView engines for administration

Or change parameter in QVDistributionService.exe.config file located in C:\Program Files\QlikView\Distribution Service folder. Parameter is QvbWaitTimeoutMinutes

    <!-- The number of minutes to wait for a free Qlikview engine -->

    <add key="QvbWaitTimeoutMinutes" value="45"/>
