ProgramData\Solarwinds\JobEngine.v2 directory using excessive disk space

Saw something similar to this posted in NPM but no one ever answered it.  Maybe someone here can.

On some of our servers being monitored I have found the C:\ProgramData\Solarwinds\JobEngine.v2\logs directory can have over 40k files and 17GB of disk. The dates on the files start from early this year.  It is filling up drives and causing them to crash.

Does anyone know what they are? Why they are created? Can they be suppresses and/or deleted?
