Meaning of /var/log/messages
I am getting a lot of message as follows in /var/log/message files as follows.
Code:
 messages.1:559:May  4 20:01:56 SERVER2 kernel: session_stat: sync=0 async=33 aretr=0

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

Code:
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:

Code:
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.

Code:
 cat /proc/sys/kernel/printk

It shows,
Code:
 6    4   1   7
