An Adequate Intake (AI) for Total Fiber in foods is set at 38 and 25 g/d for young men and women, respectively .... There was insufficient evidence to set a Tolerable Upper Intake Level (UL) for Dietary Fiber or Functional Fiber.

Consumption of viscous fibers delays gastric emptying ... thus slowing
the process of absorption once in the small intestine .... A slower emptying rate means delayed digestion and absorption of nutrients...resulting in decreased absorption of energy (Heaton, 1973). For example, Stevens and coworkers (1987) showed an 11 percent reduction in energy intake with psyllium gum intake.

So it looks like, if you eat something with nutrients and fiber at the exact same time, you might absorb a slightly smaller amount of the nutrients. But it doesn't affect things at other times in the day, there's no upper limit to how much fiber you can have (I'm sure somebody could manage to have too much, but only if they tried really hard and ate nothing else), and a bowl of flaxseed is definitely not going to kill you. Half a cup of ground flaxseed only has 16 grams of fiber, that's not even a day's recommended minimum.
