  • master-master - 1 server crashed

    Hey guys, so something odd happened today: I am running the Percona cluster on a centos 6.5 64bit, on 2 servers in a master-master config.

    Today 1 of the servers went down with the following error: http://pastebin.com/iTfbnTXS which is not really that descriptive. The servers are on low load and i have 16 gb of ram on each, so it's highly unlikely to be a resource issue.

    I also keep getting these errors:

    Code:

    I am looking in the gra files and all i see is :

    HTML Code:

    Any help would be appreciated.

    Thanks

    just happened once again, this time on the other server:

    19:32:30 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=134217728
    read_buffer_size=8388608
    max_used_connections=17
    max_threads=202
    thread_count=19
    connection_count=2
    It is possible that mysqld could use up to
    key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 15027185 K bytes of memory
    Hope that's ok; if not, decrease some variables in the equation.

    where mysqld died. If you see no messages after this, something went
