We operate Percona XtraDB cluster of three servers version: 5.5.34-31.1, Percona XtraDB Cluster (GPL), Release 31.1, wsrep_25.9.r3928
On a database having table with following structure:
CREATE TABLE `docStatsDetail` (
`date` date NOT NULL,
`adId` varchar(36) COLLATE utf8_slovenian_ci NOT NULL,
`userId` varchar(100) COLLATE utf8_slovenian_ci DEFAULT NULL,
`adImpressions` int(11) DEFAULT '0',
`adClicks` int(11) DEFAULT '0',
`ts` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
PRIMARY KEY (`date`,`adId`),
KEY `TS` (`ts`),
KEY `_adId` (`adId`),
KEY `_userId` (`userId`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_slovenian_ci;
The table has 120 mio records and if we try to delete from this table more than 20 mio records using: DELETE FROM docStatsDetail LIMIT 20000000; the server crashes with a crash report:
10:57:55 UTC - mysqld got signal 7 ;
This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
Please help us make Percona XtraDB Cluster better by reporting any
bugs at https://bugs.launchpad.net/percona-xtradb-cluster
key_buffer_size=134217728
read_buffer_size=2097152
max_used_connections=14
max_threads=102
thread_count=10
connection_count=10
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 759054 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
