Tim Armstrong commented on IMPALA-9667:
---------------------------------------
I'm still seeing this issue occasionally. I looked at the debug JSON dumps and
it seems to be lingering sessions from test_insert_mem_limit - we got lucky and
the current db for the session is a unique database:
{noformat}
