Description
Hello!
We are having issues with a replica crashing. I have attached the error log as an attachment. We have a 1 master, 2 replica setup. One of our 2 replicas crashed (mysql died out of nowhere – keep in mind this only happened on 1 replica) over the weekend and will not catch up on replication. MySQL starts and we can initiate a 'start slave', however, after a period of time mysqld crashes with the backtrace attached and we have to 'start slave' again. The slave is now 5 days behind in replication and will not stay alive long enough to catch up.
I upgraded the replica from 10.3.14 to 10.3.16 to see if it would fix the issue, but it still occurs on 10.3.16.
Any ideas?
