Mass crashes of MySQL APIs (mysqld).

We are using the MySQL Cluster 7.4.9 open source edition. Downloads mysql-cluster-gpl-7.4.9-solaris10-x86_64.tar.gz repetitively mysql-cluster-gpl-7.4.9-solaris11-x86_64.tar.gz.

Our environment are 36 MySQL API (mysqld) on Solaris 10 an 24 MySQL API (mysqld) on Solaris 11. 16 MySQL Cluster Nodes (ndbmtd) all on Solaris 11 and two MySQL Cluster Manager (ndb_mgmd) on Solaris 10.

We are experiencing mass crashes of MySQL API (mysqld) from time to time. E.g. on October 8th, 2016 15 MySQL API (mysqld) between 21:23:17 and 21:23:18 UTC.

One example:


21:23:17 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.

It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 2603761 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...

Please read
and follow instructions on how to resolve the stack trace.
Resolved stack trace is much more helpful in diagnosing the
problem, so please do resolve it

Trying to get some variables.
Some pointers may be invalid and cause the dump to abort.
Query (9abb7348): UPDATE alive SET last = UNIX_TIMESTAMP(), processnameid = 10256132,active=1 WHERE id = 10256132 AND @query:=0437
Connection ID (thread ID): 13123

The manual page at contains
information that should help you find out what is causing the crash.


The other 14 looking identical just different query's and/or mysql-cluster-gpl-7.4.9-solaris10-x86_64 in case of Solaris 10.

We do not know if it is just a coincidence, but we observed 'Got error 4010 when reading table' messages before the crash in > 90% in the minutes before the crashes. The log files of the MySQL API (mysqld) who didn't crash do not have these error at all.

Does someone can shed some light on these issue?
