Hello Babynus,

Cron in background task stops after 30 seconds and doesn't restart anymore.

I think there is a bug in "projeqtor_set_time_limit($timeout)" function and "tool/projeqtor.php" file :
if ($max != 0 && $timeout > $max) { // Don't bother if unlimited
@set_time_limit($timeout);
}

By default, PHP sets the time limit to 30 seconds. Before running cron, Projeqtor executes projeqtor_set_time_limit(0);, $max is 30s by default and $timeout is 0, so @set_time_limit is not executed and time limit stay at 30s.

Regards,
