I had major issues with this about a year ago.
The solution is to enabled nscd on all nodes, including the machine running pbs_server and the machine running maui.

Hello,

We have a chronic issue with maui scheduler. Sometime, it stops by itself and we have to restart maui.
You can find below the error messages I found in maui and torque logs.

maui log :

01/14 17:17:15 MStatClearUsage([NONE],Active)

*torque log :

Could you please help us to understand and to fix this issue ?

Thank you,
Best regards,
