Hello, I have several MariaDB 10.1.45 instances running in Linux containers with memory limits. This week I have enabled binary logging on all of them with the following parameters: log-bin = mysqld-bin binlog-format = mixed expire_logs_days = 1 After that I have been getting several errors like this in a few of them: [ERROR] mysqld: Error writing file 'mysqld-bin' (errno: 11 "Resource temporarily unavailable") A few also show these other two errors mixed with the previous one: [ERROR] mysqld: Error writing file 'mysqld-bin' (errno: 12 "Cannot allocate memory") [ERROR] mysqld: Error writing file 'mysqld-bin' (errno: 0 "Internal error/check (Not system error)") It gets stuck on this state, reporting errors to every attempt of executing a query. A restart on the service seems to solve the problem, at least temporarily. Does anybody have a clue on why it gets stuck like that? If the container ran out of memory, should not mariadb crash? I could not find any information about this error and binary logs being related. Thanks in advance, Gustavo Vieira
