Percona群集信号11

我们有一个Percona集群，它随机在不同的集群节点上获取信号11。 我已经用尽了我知道的。 这是带有信号11的.err文件。

我们正在运行服务器版本：5.6.22-72.0-56 Percona XtraDB集群（GPL），版本rel72.0，修订版978，WSREP版本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. Thread pointer: 0x4efe2a0 Attempting backtrace. You can use the following information to find out where mysqld died.
