I'have a database version MonetDB Database Server Toolkit v1.1 (Jun2016-SP2) working on RHEL version 6.7 I faced with unexpected shut down with the message in the log: "database was killed by signal SIGSEGV" when trying to execute bunch of 'SELECT COUNT(1) FROM ' quires in single connection. Tables are huge 8Mln rows and 4000 columns. Also I can't fulfill statistics table for such tables.
