InnoDB: Have you moved InnoDB .ibd files - Error

[sunyl]

Hello,

Mysql error logs shows -

InnoDB: Have you moved InnoDB .ibd files around without using the
InnoDB: commands DISCARD TABLESPACE and IMPORT TABLESPACE?
InnoDB: It is also possible that this is a temporary table #sql...,
InnoDB: and MySQL removed the .ibd file for this.
InnoDB: Please refer to
InnoDB: MySQL :: MySQL 5.0 Reference Manual :: 13.2.13.3 InnoDB General Troubleshooting
InnoDB: for how to resolve the issue.
110505 15:14:52 InnoDB: Started; log sequence number 3 3095295183
110505 15:14:52 [Note] /usr/sbin/mysqld: ready for connections.
Version: '5.0.92-community' socket: '/var/lib/mysql/mysql.sock' port: 3306 MySQL Community Edition (GPL)

InnoDB is enabled on the server and Mysql service restarts fine, but not sure why this error came up suddenly.

Any help would be much appreciated.

Do you have .ibd files on the machine?

find /var/lib/mysql -name *.ibd

You'll need to get a list of the existing .ibd files first.

Next, what are the contents of /etc/my.cnf file?

cat /etc/my.cnf

Yes, there are some .ibd files in mysql folder

root@server [~]# find /var/lib/mysql -name *.ibd | wc -l
4528
root@server [~]#

Here is my my.cnf

Tristan, what could be the issue as mysql service crashes every now and then..

[cPanelTristan]

An online check for the error indicates that someone moved an .ibd table improperly and caused the error, but I'm not entirely certain how to tell which table is the one that is the issue.

Also I see lots of process and mysql service is not working -

We'd to kill the pid's and restart mysql service to make it working.. it happens more offen every now and then.
