The rc8 server is vanilla WiredTiger with no special options:
numactl --interleave=all /home/buzz/3.0.0-rc8/bin/mongod --storageEngine=wiredTiger --port 37017 --dbpath /data/4/data0/db0 --logpath /tmp/mongo0.log --fork
Program is performance test. It generates load for a state-event model like this:
1. Find an item in the currentPos collection using findAndModify to "logically reserve" it
2. Copy it to historicPos collection
3. Insert an event doc into the events collection
4 findAndModify the same item in currentPos to write updated data
There are 32 threads. Each thread has a loop that randomly picks a position key and goes thru the steps outlined above.
Failure occurs about 90% of the time between 3000 and 7000 turns of the crank (1-4 above).
This seems to be the start of trouble:

***aborting after fassert() failure
Interesting note: Same test program (but 16 threads instead of 32) ran OK all day yesterday (start, stop, reset, over and over) on a r3.4xlarge AWS instance running ami-d13845e1.
