I am getting a lot of message as follows in /var/log/message files as follows.

Can some body tell me what is the meaning of this messages are? Actually I was having some customized application malfunction at the same time this message appears.I need to analyze the same.For that I need the information regarding meaning of these messages.

What is the current log level of your kernel set to?

loglevel=       All Kernel Messages with a loglevel smaller than the
                    console loglevel will be printed to the console. It can
                    also be changed with klogd or other programs. The
                    loglevels are defined as follows:

                    0 (KERN_EMERG)          system is unusable
                    1 (KERN_ALERT)          action must be taken immediately
                    2 (KERN_CRIT)           critical conditions
                    3 (KERN_ERR)            error conditions
                    4 (KERN_WARNING)        warning conditions
                    5 (KERN_NOTICE)         normal but significant condition
                    6 (KERN_INFO)           informational
                    7 (KERN_DEBUG)          debug-level messages

Please post the output of:

cat /proc/sys/kernel/printk

My guess is that those log messages are 6 (KERN_INFO) informational but best to analyze your log levels first.

3 
 cat /proc/sys/kernel/printk

It shows,

 6    4   1   7
