> Currently when we run out of memory, we logged the memory usage of all the running queries on the segment where OOM happened. However, if runaway termination successfully terminates the biggest offender, before we hit OOM, we do not have any logging mechanism. This left us with insufficient information for root cause analysis of memory leaks.
