Low sgcr can crash Eclipse

[berland]

The following table will crash with a fatal monotonicity error in Eclipse 100.
The reason being the second SG value which is too small, manual does not declare what are the accuracy limits in E100.

Quick workaround is to set sgcr to zero or to something larger (1e-5 or 1e-4)
