mysqld: /home/stepan/mariadb/10.4/git/wsrep-lib/src/transaction.cpp:123: int wsrep::transaction::start_transaction(const wsrep::transaction_id&): Assertion `active() == false' failed.

191106 15:41:05 [ERROR] mysqld got signal 6 ;

Server version: 10.4.9-MariaDB-debug-log (edited) 

key_buffer_size=134217728

read_buffer_size=131072

max_used_connections=2

max_threads=153

thread_count=10

It is possible that mysqld could use up to

key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 467842 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...
