I saw LSM failures running test/format in the develop branch when truncate is configured, for example:
t: read_row: row 7: found in Berkeley DB, not found in WiredTiger t: read_row: row 4: found in Berkeley DB, not found in WiredTiger
WT_SESSION.truncate was just recently merged into format, and I'm pretty suspicious that's the issue. The CONFIG file is the same as WT-3927, which usually hangs, but I'm seeing it fail maybe 20% of the time.
The CONFIG file:
