[global] [error] Indeterminant linear system detected while working near variable #71

[global] [error] Indeterminant linear system detected while working near variable 8646911284551352423 (Symbol: x103).

Thrown when a linear system is ill-posed. The most common cause for this error is having underconstrained variables. Mathematically, the system is underdetermined. See the GTSAM Doxygen documentation at http://borg.cc.gatech.edu/ on gtsam::IndeterminantLinearSystemException for more information. What is the cause, how to deal with it, thank you.
