Mongod crashes with a signal 11 (Segmentation fault) while running a map/reduce job.

We have 2 nodes in replica with an arbiter. The first node crashed yesterday 19:30 and the second node took over, just like it should.

Unfortunately the second node crashed as well at 06:35 this morning.

Here are the stacktraces and errors:

node1:
