Hi , 

I am attaching a log of Cplex 12.7 solve on a MIP problem. 

The number of iterations on node 62 is 118123 

The number of iterations on node 64 is 114169. 

It is suspected that there is a bug in the mip parallelization part, where some piece of synchronization does wrong.

Otherwise, the number of simplex solve iteration should increase overtime. 

Are I mistaken somewhere?

Thank you for reporting this. This is indeed a bug. We reproduced it here and are working on a fix.
