[Help-glpk] Does it mean no optimal solution is found??

[Eren Gurses]

Hello,
I create an LP problem by specifying an objective function and some
constraints. Some of my parameter sets yield optimal solutions for this
LP problem, however in some cases I got the following output, which
cannot find any optimal solution after the last parameter becomes (0),
and after that point it loops infinitely by giving the "spx_prim_chuzc:
recomputing basic solution components" debug output.

Does this mean there is no optimal solution for this LP problem, or may
it be some kind of a bug that I can correct it?? By the way I am just
using glpk to solve my problem, so I am not an LP theory expert. Please
excuse me for the incovenience.
