Hello,

i m solving a big MIP with OPL 6.3 / CPLEX 12.1

in the end of the optimisation, i got this message error:
Error 1013: Bad parameter number for CPLEX parameter routine

The engine log ends by:
Warning: MIP starts not constructed because of out-of-memory status

I ve copied/pasted the engine log:

Tried aggregator 2 times.
MIP Presolve eliminated 104843 rows and 812260 columns.
MIP Presolve modified 23866 coefficients.
Aggregator did 25434 substitutions.
Reduced MIP has 28358 rows, 45839 columns, and 223039 nonzeros.
Reduced MIP has 6260 binaries, 0 generals, 0 SOSs, and 0 indicators.
Presolve time = 3.06 sec.
Clique table members: 2.
MIP emphasis: balance optimality and feasibility.
MIP search method: dynamic search.
Parallel mode: deterministic, using up to 4 threads.
Root relaxation solution time = 1.14 sec.

Error 1013 means that you specified an invalid argument to one of the
parameter setting routines. What API do you use (C, C++, Java, interactive, ...)?
What parameters do you explicitly set and to which values?
