How can I get more detail on the outputs from MultiStart Optimization?

I am currently using MultiStart for a global optimization problem. My question pertains to the output, and finding out more from this.

Specifically, from 3600 start points (user-defined), there are 1600 "localSolverSuccess" and 2000 "localSolverNoSolution" outputs. I am able to see the success outputs within the "manyminsm" array.

However, I am interested in why the other 2000 failed to find an optimum. How am I able to find more information out from these? For example, the flag value pertaining to why they did not succeed, and the starting values used.

The reason I am after this information, is not only for understanding the results more, but because for all the different data (I am running this on different data sets i.e. different subjects), the number of successes (1600) and no successes (2000) are the same across all data sets.
