Hi, I am running an optimization problem in python using pyomo 4.3.11388 and the GLPK solver 4.57 on Windows 7. While running 8 calls in parallel with multiprocessing.Pool GLPK has a rare write problem to the \Users \user\AppData\Local\Temp folder: This happens only once out of more than thousands of successful runs. Anyone can help? Thanks! ERROR: "[base]\site-packages\pyomo\opt\base\solvers.py", 575, solve Solver log: GLPSOL: GLPK LP/MIP Solver, v4.57 Parameter(s) specified in the command line: --write C:\Users\JGOREN~1\AppData\Local\Temp \tmp4fo_8eqx.glpk.raw --wglp C:\Users\JGOREN~1\AppData\Local\Temp \tmps7viej_q.glpk.glp --cpxlp C:\Users\JGOREN~1\AppData\Local\Temp \tmpjnqvqljx.pyomo.lp Reading problem data from 'C:\Users\JGOREN~1 \AppData\Local\Temp\tmpjnqvqljx.pyomo.lp'... 25 rows, 45 columns, 69 non-zeros 223 lines were read Writing problem data to 'C:\Users\JGOREN~1 \AppData\Local\Temp\tmps7viej_q.glpk.glp'...
