Description:
5.7.27 slave, an assertion error occurred executing the command "stop slave or shutdown()".

2020-03-10 11:13:04 0x2b1a33ba4300  InnoDB: Assertion failure in thread 47391536988928 in file trx0rseg.cc line 134
InnoDB: Failing assertion: UT_LIST_GET_LEN(rseg->update_undo_list) == 0
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

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=16777216
max_used_connections=83
max_threads=3000
thread_count=0
connection_count=0
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 147504340 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 Anthony,

This is not a software bug, this is a memory corruption bug that caused InnoDB to crash. Do you have registered ECC RAM on your server or you are running a plain RAM without any error checking? Chance of this crash happening again is very slim and not much we can do about it. If, on the other hand, you do run your server with error checking RAM then we really need to know what you did and how to reproduce this.

Stay safe
Bogdan
