It does not explain why it works under low load and not under high load. However, I seem to have found something. When I started phpMyAdmin and selected one of the database, the server went away again and I found this in /var/log/syslog: Oct 12 11:53:33 cebycny mysqld: 131012 11:53:33 InnoDB: Assertion failure in thread 140182892447488 in file ../../../storage/innobase/handler/ha_innodb.cc line 8066 Oct 12 11:53:33 cebycny mysqld: InnoDB: Failing assertion: auto_inc > 0 Oct 12 11:53:33 cebycny mysqld: InnoDB: We intentionally generate a memory trap.
