Jump in Residuals

I am using FLUENT to run a 2-D laminar natural convection problem. While I was running the simulation I noticed a couple of strange jumps in the residuals after about 14000 iterations and again after about 17500 iterations. The residuals return to where they were after a few iteration, but I was wondering if anyone knows why it would do this.
P.S. I'm trying to attach a picture to show a plot of the residuals.

Judging after your residuals your solution is converged, the oscillations between 1e-08 and 1e-10 probably means you are at the limit of your machine precision, I think they are not looking strange.
If I'm wrong please correct me,
