This message is generated when the value of the AccuracyGoal option is too large to be reached using machine precision.
This error can usually be corrected by raising the value of the WorkingPrecision option, lowering the value of the AccuracyGoal option, or using better starting values.
In high-precision calculations, the precision of any numbers in the input should be as high or higher than the value of the WorkingPrecision option.
Off[message] switches off the message; On[message] switches it on. For example: Off[FindRoot::frmp].
