2023-05-13 06:33:59 0x7f2da3627b38  InnoDB: Assertion failure in file /home/buildozer/aports/main/mariadb/src/mariadb-10.6.12/storage/innobase/trx/trx0trx.cc line 1270

InnoDB: Failing assertion: UT_LIST_GET_LEN(lock.trx_locks) == 0

InnoDB: We intentionally generate a memory trap.

InnoDB: Submit a detailed bug report to https://jira.mariadb.org/

InnoDB: If you get repeated assertion failures or crashes, even

InnoDB: immediately after the mariadbd startup, there may be

InnoDB: corruption in the InnoDB tablespace. Please refer to

InnoDB: about forcing recovery.

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: 10.6.12-MariaDB-log source revision: 4c79e15cc3716f69c044d4287ad2160da8101cdc

key_buffer_size=134217728

read_buffer_size=131072

max_used_connections=89

max_threads=153

thread_count=42

It is possible that mysqld could use up to

key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 467967 K  bytes of memory

Hope that's ok; if not, decrease some variables in the equation.

Thread pointer: 0x7f2da14bef88

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...

Cannot determine thread, fp=0x49000, backtrace may not be correct.

Bogus stack limit or frame pointer, fp=0x49000, stack_bottom=0x7f2da3630000, thread_stack=299008, aborting backtrace.

Trying to get some variables.

Some pointers may be invalid and cause the dump to abort.
