How often should a BI 4.x environment be restarted

Hi Everyone,

Could you plz help me understand how often should a BI 4.x environment be restarted and based on what factors?

Is it good to restart daily, once a week..??

We are seeing some issues with scheduling jobs going into running state and getting hung. So I am trying to find a frequency of how often should I keep restarting my environment to ensure they jobs run fine. Please help!!

Environment details:

BI Version: 4.1 SP5

Windows 2012 R2

Thanks,

satya
