異なるクラスターノードで信号11をランダムに取得しているperconaクラスターがあります。私は私が知っているすべてを使い果たしました。これがシグナル11の.errファイルです。
サーバーバージョンを実行しています:5.6.22-72.0-56 Percona XtraDB Cluster(GPL)、リリースrel72.0、リビジョン978、WSREPバージョン25.8、wsrep_25.8.r4150
11:01:11 UTC - mysqld got signal 11 ;
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=536870912
read_buffer_size=131072
max_used_connections=17
max_threads=153
thread_count=6
connection_count=3
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 585348 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

in the manual which will help you identify the cause of the crash.
ありがとう!
私たちが見つけた唯一の修正は、バージョンを5.6から5.5にドロップすることでした。
その後、別の信号11はありませんでした。
ありがとう、
テーブルロック
Galera Clusterは、マルチマスターレプリケーションと競合するため、テーブルロックをサポートしていません。そのため、LOCKTABLESおよびUNLOCKTABLESクエリはサポートされていません。これは、同じ理由でGET_LOCK()やRELEASE_LOCK()...などのロック関数にも当てはまります。
