> {code}
> As GraphX uses cached RDDs intensively, the issue is only reproducible when previously cached and checkpointed Vertex and Edge RDDs are evicted from memory and forced to be read from disk. 
> For testing purposes the following parameters may be set to emulate low memory environment
> {code}
> val sparkConf = new SparkConf()
>   .set("spark.graphx.pregel.checkpointInterval", "2")
>   // set testing memory to evict cached RDDs from it and force
>   // reading checkpointed RDDs from disk
>   .set("spark.testing.reservedMemory", "128")
>   .set("spark.testing.memory", "256")
> {code}
> This issue also includes SPARK-22150 and cannot be fixed until SPARK-22150 is fixed too.
