[Scip] One small question

[Rostislav Stanek]

Dear SCIP community,
I have a small question: If I get the following output:

[linear] <subtour#0>: 0 <= <x#6#1>[B] +<x#41#1>[B] +<x#41#6>[B] <= 2;
violation: right hand side is violated by 1
[linear] <subtour#0>: 0 <= <x#6#1>[B] +<x#41#1>[B] +<x#41#6>[B] <= 2;
violation: right hand side is violated by 1,

what does it mean “violation: right hand side is violated by 1”? Does it 
mean that something in the solving process went wrong? Or is it a 
correct output?

Thank you very much in advance.

Yours faithfully,
Rostislav Stanek
