I have strange problem, we are using circulation replication, between 2 different network with 5.6.25 and 5.6.22 version of MySQL and RAM is 64GB with 45GB
Master Server is running MySQL 5.6.25
Replication path is:
server A 5.6.25 (Flash Drive) -> server B 5.6.22 (Normal HDD) -> Server C 5.6.25 (Flash Drive) -> server A 5.6.25 (Flash Drive).
In testing phase all are well but after deploying application to server A 5.6.25, MySQL of Server A is frequently restart and at that time RAM consumption is 88%.
Error log show nothing.
After MySQL restart, error log show:
