FusionServer hangs when calling resetWithNewParams

[mpowelson]

This was happening yesterday, but it does not appear to be happening this morning. Intermittently, it would hang when calling resetWithNewParams several times in a row. Debugging it, it looked like it was getting stuck at cudaFreeHost (). Based on this, I am thinking this may pop up again when my GPU memory gets in the the right state again.

Here is the full backtrace from where it got stuckbacktrace.txt
