we are running CPLEX(R) Interactive Optimizer 126.96.36.199 on a Debian 6.0.7 (64bit) server. When we try to solve the model tmp.sav, we get the error message "3019 Failure to solve MIP subproblem". The log files coincide with the visual output of the interactive optimizer and do not allow a more precise problem analyses. Enclosed you find the tmp.sav, which is the debug output of our java-application.
We would appreciate it if you could tell us about a work arround or if you could tell us how to obtain a more precise problem analysis.
Sincerely, Johannes and Martin
