attached backtrace taken at this point. As no RPM build of debug symbols this is missing symbols still (MDEV-4646). Using an objdump analysis like MDEV-8108 will probably point to the relevant lock.
Using MDEV-7126 as basis for test:
no response from:
show global variables show global variables like 'replicate_i%'; show global status like 'Bytes_%'; show global status like 'Busy_%'; show global status like 'x%';
