    Description

      Build
      4.5.0-2363

      Testcase
      ./testrunner -i INI_FILE.ini -p get-cbcollect-info=True,get-coredumps=True,get-logs=False,stop-on-failure=False,GROUP=P1 -t fts.stable_topology_fts.StableTopFTS.index_query_in_parallel,items=1000000,num_queries=200,GROUP=P1

      The first crash is noted after query #40. This is when the indexing is still happening. Copying testlog - https://gist.github.com/arunapiravi/be2cfeff75a96d859af9bd1db4ebe858

      Multiple crashes seen in few mins. Kernel panics on vm and it goes offline. This may not be reproducible again. I've saved all breakpad dump files at 172.23.107.187:/root/new_assert/
