Opened: Sep 22, 2020 Severity: 3-Major
1) var/lib/mysql/mysqld.err is filled with log entries that contain: ------------ 200824 11:04:43 [ERROR] mysqld: Can't open file: './PRX/REQUEST_LOG.frm' (errno: 24) 200824 11:18:46 [ERROR] mysqld: Can't open file: './PRX/REQUEST_LOG.frm' (errno: 24) 200824 11:35:58 [ERROR] mysqld: Can't open file: './PRX/REQUEST_LOG.frm' (errno: 24) ------------ 2) There are a lot of PRX.REQUEST_LOG partitions, in some cases up to 1024, many of which are empty.
MySQL runs out of resources when opening the file PRX.REQUEST_LOG and an error message states the file is corrupt.

1. If the /appdata partition is filled to 100% and MySQL restarts continuously, refer to the following Knowledge Articles: https://support.f5.com/csp/article/K14956 https://support.f5.com/csp/article/K42497314 2. To identify the empty partitions, look into: mysql -su root -p$(perl -MPassCrypt -nle 'print PassCrypt::decrypt_password($_)' /var/db/mysqlpw) -e "SELECT * FROM INFORMATION_SCHEMA.PARTITIONS WHERE table_name = 'REQUEST_LOG' AND table_schema = 'PRX'\G" 3. For every partition that is empty, manually (or via shell script) execute this sql: mysql -su root -p$(perl -MPassCrypt -nle 'print PassCrypt::decrypt_password($_)' /var/db/mysqlpw) -e "ALTER TABLE PRX.REQUEST_LOG DROP PARTITION <empty_partition_name>;" Note: <empty_partition_name> must be substituted with the partition name, for example p100001. 4. Increase 'open_files_limit' to '10000'. -------------------------------- In the /etc/my.cnf file: 1. Change the value of the 'open_files_limit' parameter to 10000. 2. Restart MySQL: bigstart restart mysql -------------------------------- 5. pkill asmlogd Note: This workaround does not survive upgrade. It must be reapplied after every upgrade until the upgraded version contains a fix.
This release increases the default 'open_files_limit' to '10000'.
