Have: Percona 5.6.20-rel68.0.el5
Upgraded to: Percona 5.6.21-rel69.0.el5
OS: RHEL 5.11
Replication: Percona slaves replicating off of a MySQL (community) 5.1.61 server.
Symptom: MySQL process constantly restarting. Not all of the slave servers restarted at the same time intervals.
Question: What is going wrong? Did Percona change anything between these versions that don’t handle using HugeTLB memory chunks set aside in the kernel for MySQL?
Attached is a slightly sanitized version of the *.err log
