DeanWhitehouse Posted September 3, 2012 Author Share Posted September 3, 2012 This is a server set up issue not an Amazon issue. We've solved the issue slightly by switching to InnoDB which only locks per row but we still experience crashes regularly.

spec36 Posted September 12, 2012 Share Posted September 12, 2012 Hey I had this issue on my server yesterday, but it was SNMPd that showed locked up. This is what I did to resolve it. 1. cd /var/lock/subsys 2. delete snmp or mysql in your case 3. service snmpd start Looks like this happens when the current running process somehow gets corrupt and then someone tries to restart it, but the PID is already in use by the original process and that is why you get the subsys locked message. Hope this helps. Link to comment https://forums.phpfreaks.com/topic/267424-mysql-dead-but-subsys-locked-amazon-ec2/#findComment-1377446 Share on other sites More sharing options...
