10.2.6
Description
I am randomly running to crashes on a pair of master/master maria 10.2.6 instances. Below is the output of the crash in the log. I do not seem to be getting cores for these crashes but the backtrace is in the log output. also note the query on each crash is the same type of data into the same table each time. I am at a loss, and not sure how to proceed, so any suggestions would be appreciated.
log output of crash.

InnoDB: Failing assertion: lock != m_wait_lock || (innodb_lock_schedule_algorithm == INNODB_LOCK_SCHEDULE_ALGORITHM_VATS && !thd_is_replication_slave_thread(lock->trx->mysql_thd))

InnoDB: We intentionally generate a memory trap.

|
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 https://mariadb.com/kb/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: 10.2.6-MariaDB-log

key_buffer_size=134217728
|
read_buffer_size=1048576
|
max_used_connections=61
|
max_threads=4098
|
thread_count=70
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 8610069 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.
