Thomas Daugherty added a comment - 2015-07-11 00:02 - edited Just wanted to comment that I'm having this same issue. Stored procedures to drop/create partitions runs once per day. A few times a week a node will crash within a minute of the procedure running. This is a database for a Zabbix install, I'm using the stored procedures referenced above. Please let me know if there are any data you'd like me to submit. Edit: Using 10.0.16

Jeff Gilbertson added a comment - 2015-07-15 23:09 Just a comment to say that I'm having the issue, too, exactly as described above.

DD Brown added a comment - 2015-07-15 23:28 This seems to be coming more of an issue in our environment. What started out as once every couple of months seems to be increasing in frequency. It is now happening several times a week.

Thomas Daugherty added a comment - 2015-07-30 00:22 Elena Stepanova and Vicentiu Ciorbaru , Would it be possible to get this bug looked at again? It's really causing havoc for us. Its happening twice a week or more right after the create/drop partition stored procedure runs. neominder_sqlcrashlog.txt

Eugen O added a comment - 2015-08-29 00:29 Hi, I've hit the same situation, stack trace looks like this : 150827 5:28:54 [ERROR] 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. To report this bug, see http: //kb.askmonty.org/en/reporting-bugs 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. Server version: 10.0.20-MariaDB-log key_buffer_size=536870912 read_buffer_size=131072 max_used_connections=62 max_threads=1502 thread_count=34 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 3822319 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. Thread pointer: 0x0x19a89bf8 Attempting backtrace. You can use the following information to find out where mysqld died.
