Hi List, Sometimes, my mysqld daemon begin to consumes 100% the connection to the server gets unstable and I get flooded in the mysql error log with these messages: Nov 4 06:17:01 db1 mysqld: 2015-11-04 6:17:01 140682979031168 [ERROR] Error in accept: Bad file descriptor Nov 4 06:17:01 db1 mysqld: 2015-11-04 6:17:01 140682979031168 [ERROR] Error in accept: Bad file descriptor Nov 4 06:17:01 db1 mysqld: 2015-11-04 6:17:01 140682979031168 [ERROR] Error in accept: Bad file descriptor Nov 4 06:17:01 db1 mysqld: 2015-11-04 6:17:01 140682979031168 [ERROR] Error in accept: Bad file descriptor Nov 4 06:17:01 db1 mysqld: 2015-11-04 6:17:01 140682979031168 [ERROR] Error in accept: Bad file descriptor Nov 4 06:17:01 db1 mysqld: 2015-11-04 6:17:01 140682979031168 [ERROR] Error in accept: Bad file descriptor it only stops when I restart the daemon, no query is shown in "show full processlist".

Hello, A new question has been asked in "Upgrading MariaDB" by areno. Please answer it at http://mariadb.com/kb/en/downgrade-mariadb/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- Hello, I recently upgraded MariaDB 10.0.21 to 10.1.8. Our program that interacts with it is tossing errors and we found out it's not supported by the program. We were directed from the application dev team to install 10.0.21 back. I cannot find any documentation on how to properly downgrade the DB and move the data to an older version. Any specific process to follow? -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/downgrade-mariadb/

[Maria-discuss] Slave SQL: Fatal error: ... Slave SQL Thread stopped with incomplete event group having non-transactional changes
by Reindl Harald 29 Oct '15

* why does that happen at all instead finish whatever is not finished after get SIGTERM * "try to restart the slave with --slave-exec-mode=IDEMPOTENT" must be a joke when "slave-exec-mode = IDEMPOTENT" is part of my.cnf for years *because* of that failure happening randomly when stop a slave at a wrong moment 151029 9:15:44 [ERROR] Slave SQL: Fatal error: ... Slave SQL Thread stopped with incomplete event group having non-transactional changes. If the group consists solely of row-based events, you can try to restart the slave with --slave-exec-mode=IDEMPOTENT, which ignores duplicate key, key not found, and similar errors (see documentation for details). Gtid 0-1-2058483, Internal MariaDB error code: 1593

[Maria-discuss] New Question: MariaDB Error Code -> Windows ERRORLEVEL
by AskMonty KB 26 Oct '15

26 Oct '15

Hello, A new question has been asked in "Error Codes" by patkoshar. Please answer it at http://mariadb.com/kb/en/mariadb-error-code-windows-errorlevel/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- Hello, Is there a known issue or problem with how/when MariaDB returns error codes from calling '--execute' on *.sql scripts in Windows? It seems like certain errors are detected and returned as such, and others are not. For example, a *.sql file of completely random bytes will set the Windows ERRORLEVEL=1 after failing, reporting the following error: ERROR: ASCII '\0' appeared in the statement... Another *.sql file that references an unknown database will set the Windows ERRORLEVEL=0, but still textually report an error after failing: ERROR 1049 (42000) at line 1 in file... Any ideas? Thank you! -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/mariadb-error-code-windows-errorlevel/
