Server Details :
Operating system :
Centos 6.2 linux server, Memory : 4GB Swap Size : 2GB
Steps taken to resolve the Issue
Enabled innodb_force_recovery=4 to commit the .ibd files and to mysql server.
Tried installing MYSQLTUNER to monitor query activities.However cudnt install it.
Have to manually restart it after it shuts down. Not able to restart it automatically using mysqlsafe Have been seeing this issue since past few days and also a suspect spike in number of hits which reflects in my AW stats. Will appreciate if someone help me know where to look for solutions and help me configure the mysql config file for a proper performance and memory usage.
