Issue has also been filed in alpine packages
The following issue appeared with mariadb 10.5.8 (there is no issue with alpine 3.12 and mariadb 10.4.x):
- On arm v7 (32 bits) mysqld consumes about 100% cpu when idle, but still works.
- On arm v8 (64 bits) or amd64, it consumes near 0% cpu when idle as expected.
I see only one difference in start logs (but that may be irrelevant):
- arm v7 : "Using generic crc32 instructions"
- arm v8 : "Using ARMv8 crc32 instructions"
Any idea why this happens and if there is an option in mysqld to circumvent the issue?
