I am using pt-archiver for daily archiving of tables, but while selecting data from one tables I am getting following error and it restart mysql instance
2021-07-07 13:21:17 0x7fe0dffdc700 InnoDB: Assertion failure in thread 140603807352576 in file btr0pcur.cc line 46
I run pt-archiver with --dry-run and following is my select query
SELECT /*!40001 SQL_NO_CACHE */
irig_time
,device_id
,message_id
,mode
,protection_1
,protection_2
,protection_3
,protection_4
,alarm_1
,alarm_2
,alarm_3
,alarm_4
,grid_switch_control
,dc_switch_1_on
,dc_switch_2_on
,additional_feedback_external_sensor
,module_communication_fault_position
FROM acbm_status_v2_0_0
FORCE INDEX(PRIMARY
) WHERE (DATE(irig_time)=DATE_SUB(CURDATE(), INTERVAL 1 DAY)) ORDER BY irig_time
,device_id
LIMIT 200
If i run this query manually still getting assertion error and it restart mysql instance.
Following is table structure
Table: acbm_status_v2_0_0
Columns:
irig_time datetime(6) PK
device_id int(11) PK
message_id bigint(20) UN
mode varchar(64)
protection_1 int(10) UN
protection_2 int(10) UN
protection_3 int(10) UN
protection_4 int(10) UN
alarm_1 int(10) UN
alarm_2 int(10) UN
alarm_3 int(10) UN
alarm_4 int(10) UN
grid_switch_control tinyint(1)
dc_switch_1_on tinyint(1)
dc_switch_2_on tinyint(1)
additional_feedback_external_sensor tinyint(1)
module_communication_fault_position int(10) UN
Below is complete trace

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.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.
key_buffer_size=8388608
read_buffer_size=131072
max_used_connections=18
max_threads=500
thread_count=18
connection_count=17
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 206883 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
