  • 5.5.21 Crash then auto recovery again and again ,but always failed.

    I had occurred many times, error like this:

    140427 14:11:04 InnoDB: Assertion failure in thread 139751980574464 in file row0sel.c line 4619
    InnoDB: Failing assertion: trx->isolation_level == TRX_ISO_READ_UNCOMMITTED
    InnoDB: We intentionally generate a memory trap.
    InnoDB: Submit a detailed bug report to http://bugs.mysql.com.
    InnoDB: If you get repeated assertion failures or crashes, even
    InnoDB: immediately after the mysqld startup, there may be
    InnoDB: corruption in the InnoDB tablespace. Please refer to
    InnoDB: http://dev.mysql.com/doc/refman/5.5/...-recovery.html
    InnoDB: about forcing recovery.
    06:11:04 UTC - mysqld got signal 6 ;
    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.

    key_buffer_size=33554432
    read_buffer_size=131072
    max_used_connections=540
    max_threads=2000
    thread_count=193
    connection_count=193
    It is possible that mysqld could use up to
    key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 4409252 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...

    Hi,

    Can you provide full error log and output of pt-mysql-summary of this server? Are you getting this error while running some specific statement like update/alter table or something? There are few bugs related to this but I'm not sure if anyone is related to your case.
