[MDEV-8268] InnoDB: Assertion failure in file buf0buf.cc line 5842 failing assertion ut_a(free_slot != NULL); - Jira

Details

Type: Bug
Status: Closed (View Workflow)
Priority: Major
Resolution: Fixed
Affects Version/s: 10.1.4
Fix Version/s: 10.1.6
Component/s: Encryption, Storage Engine - InnoDB, Storage Engine - XtraDB
Labels:
None

Description

Found using:

innodb_read_io_threads=24
innodb_write_io_threads=24
innodb_buffer_pool_instances=32
innodb_encrypt_tables=1

Problem is that there can be more than pre-allocated number of used slots on encryption/compression because of open I/O requests.

~~MDEV-8268~~: InnoDB: Assertion failure in file buf0buf.cc line 5842 failing assertion ut_a(free_slot != NULL);

Analysis: Problem is that there is not enough temporary buffer slots
for pending IO requests.

Fixed by allocating same amount of temporary buffer slots as there
are max pending IO requests.
