Blocker Description
Build
4.5.0-2394
Testcase
./testrunner -i INI_FILE.ini get-cbcollect-info=True,get-coredumps=True,get-logs=False,stop-on-failure=False,GROUP=P0 -t fts.moving_topology_fts.MovingTopFTS.erl_crash_on_kv_during_index_building,items=30000,cluster=D,F,F,GROUP=P0
This is not going to be consistently reproducible. Same test ran fine on earlier builds but doesn't mean this is a regression.
