Our maui config does not explicitly define any resource limits: the
cpu-time limits are set in the PBS queue config.
Probably you are referring to some default maui parameters? But I could
only find RESOURCELIMITPOLICY and WCVIOLATIONACTION parameters from the
docs. Neither one has a straight forward 'disable' option.
Can you please elaborate on what you mean by disabling the resource
