Running the medium-lsm.wtperf configuration on macbook, I'm seeing:
Shutting down LSM checkpoint utility thread: Too many open files

the WiredTiger library cannot continue; the process must exit and restart
|
aborting WiredTiger library
|
cursor.set_key: the WiredTiger library cannot continue; the process must exit and restart
|
cursor.set_key: aborting WiredTiger library
|
And then an access violation.
Ran it in gdb, to collect some more information:
