      Failure of http://mjc.homeunix.org:8180/job/wiredtiger-test-format-stress/5355/
      From Keith:
      Anybody have any ideas on this one?

      The backtrace looks just wrong:

      Backtrace:
      /lib64/libc.so.6(gsignal+0x35)[0x3467632925]
      /lib64/libc.so.6(abort+0x175)[0x3467634105]
      ??:0(__wt_abort)[0x4b11fb]
      /home/jenkins/jenkins/workspace/wiredtiger-test-format-stress/build_posix/../src/support/err.c:488(__wt_illegal_value)[0x44e8ac]
      /home/jenkins/jenkins/workspace/wiredtiger-test-format-stress/build_posix/../src/lsm/lsm_cursor.c:870(__clsm_prev)[0x4a73ed]
      /home/jenkins/jenkins/workspace/wiredtiger-test-format-stress/build_posix/../src/cursor/cur_std.c:126(__wt_cursor_set_key)[0x425434]
      /home/jenkins/jenkins/workspace/wiredtiger-test-format-stress/build_posix/../src/meta/meta_table.c:200(__wt_metadata_search)[0x433152]
      /home/jenkins/jenkins/workspace/wiredtiger-test-format-stress/build_posix/../src/meta/meta_ckpt.c:72(__wt_meta_checkpoint_last_name)[0x4aff3a]

      *wt_cursor_set_key doesn't call *clsm_prev.

      The run-time failure looks more interesting:

      87: file, fixed-length column-store
      [1411241360:84808][31786:00a7df74c27f0000], t, file:wt-000004.lsm, cursor.search: read failed: 3096064/1024 is on the available list
      [1411241360:84842][31786:00a7df74c27f0000], t, file:wt-000004.lsm, cursor.search: the WiredTiger library cannot continue; the process must exit and restart

      It maybe worth running this config?

      And the config
