It appears from the message below that the CLP executable had a a
segmentation fault while running a problem that I submitted. What should a
Neos server Clp user do when they get this message ? (I am attaching the
submitted problem.)

Scheduling Production and Inventory Prolem (Chapter 12 of Chvatal).
Notation:
j = Month index j = 0, 1, 2, ... , 12 (0 for december of previous year)
d_j = estimated demand for month j
x_j = normal production level during month j
y_j = overtime production level during month j
z_j = amount of inventory from previous month during month j
t_j = hiring and firing cost for changed from month j-1 to month j
Objective:
s = 20*y1 + 8*z1 + t1 + ... + 20*y12 + 8*z12 + t12
Constraints for j = 1, ... , 12:
-.3*x_j + y_j <= 0 (12.2) a_j
x_j + y_j + z_{j-1} - z_j = d_j (12.3) b_j
-x_{j-1} + x_j <= 800 (12.8) c_j
x_{j-1} - x_j <= 800 (12.8) e_j
t_j + 15*x_{j-1} - 15*x_j >= 0 (12.10) f_j
t_j - 21*x_{j-1} + 21*x_j >= 0 (12.10) g_j
Other Constraints:
x0 = 5800 (12.6)
z0 = 0 (12.6)
z12 = 0 (12.6)
