Same problem that quite confusing(Fatal signal 6). I have found the crashing occurred while "Projected Coordinate Systems" was configured(e.g. I use Beijing 1954 3 Degree GK CM 120E in my mxd as below).
What's interesting is every service pre-defined in SDK ("mapoptions") play good, as well as my customized map service in arcgis server 10.3 using "Geographic Coordinate Systems"( I tried WGS1984 ).
Very much looking forward to your answers. Any suggestion will be appreciated.
