Hi Keith,
Can you please take a look at this failure in automated runs of test/format?
http://mjc.homeunix.org:8180/job/wiredtiger-test-format-stress/192/console
The error message is here:
file:__wt [cursor.insert]: clear hazard reference: session: 0x2339e38 reference 0x7f591c02d090: not found session.close: hazard reference: (0x7f598001c830: ../src/btree/col_srch.c, line 72) session.close: unexpected hazard reference session.close: unexpected hazard reference at session.close file:__wt [cursor.insert]: ../src/include/txn.i, 221: txn_state->id == WT_TXN_NONE file:__wt [cursor.insert]: aborting WiredTiger library
It looks like we might be trying to clear a different hazard reference than we set – the clear fails, and then there is an unexpected hazard reference left during session.close.
I don't understand why that is leading to an abort during cursor.insert, though.
Here is the config file, but I've run it a few hundred times without reproducing this:
