In** LogisticRegressionwithLBFGS**, if using origional data form http://stat-computing.org/dataexpo/2009/the-data.html without normalized and setting parameters like the following:

instances	dimensions	num of classes	iterations	convergencoTol	regparam	correction
7340025	29	10	100	1E-6	1.0	10

Error “Failure! Resetting history: breeze.optimize.FirstOrderException: Line search failed” will occur and "the result is not converged because max iterations reached".

Line search failed and the result is not converged
