Description
Maria DB crashed with a stack trace as below .
170201 17:29:39 InnoDB: Assertion failure in thread 140462023636736 in file btr0pcur.c line 257
|
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/en/forcing-innodb-recovery.html
|
InnoDB: about forcing recovery.
|
170201 17:29:39 [ERROR] 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.
|
|
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: 5.5.30-MariaDB-log
|
key_buffer_size=262144
|
read_buffer_size=8388608
|
max_used_connections=98
|
max_threads=202
|
thread_count=63
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 2485267 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.

Thread pointer: 0x0xda2c160
|
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...
