MariaDB 10.5.5 and 10.5.8 difference and innodb_lru_flush_size

I have two server.

One has Maria DB 10.5.5 and other has 10.5.8.

10.5.8 occur this error.

[ERROR] [FATAL] InnoDB: Semaphore wait has lasted > 600 second. We Intentionally crash the server because it appears to be hung.
[ERROR] mysqld got exception 0x80000003

Even if 10.5.5 server save more data, but 10.5.5 not occur error.

Both innodb_buffer_pool_size is 12G.

So I compare environment variables, and 10.5.8 has innodb_lru_flush_size variable.

It value is default 32.

What value innodb_lru_flush_size before 10.5.8?

If I increase innodb_lru_flush_size, MariaDB 10.5.8 has no more semaphore error?
