Run #13155: http://build.wiredtiger.com:8080/job/wiredtiger-test-format-stress-ppc/13155/consoleFull
gdb eventually dropped core while I was looking at this, but as far as I can tell, this is a small cache with a large number of worker threads, and all of the worker threads are spinning in __wt_cache_eviction_worker.
I'll attach the stack traces.
Here's the CONFIG:
