This has been resolved. Thank you.

/var is probably full for some reason

David,
What was done to resolve this issue?

 

[David Raper]

The /var log was full. We just restarted the server to clear the log out. We ended up setting up a nightly reboot on it because the /var log file was filling up every day or two.

You probably fixed the symptom but something is wrong if the logs are filling the /var that fast.

 

[David Raper]

We found the reason behind that too, but are limited with what we can do to resolve that issue. The reason that they are filling up that fast is because we have IP camera's that take a snapshot and store to the file system, every time motion is detected.

 

[cyberjock]

How does that affect the logs? Just wondering...

 

[David Raper]

As far as I have been able to tell, every connection writes a new line to the log file, causing it to expand in size. Because the camera's are constantly taking pictures and connecting to the fileserver, it is creating numerous lines in the var log file. The only thing we have found to be able to resolve that issue, is a daily reboot to clear the var log file. I could be wrong on how it is affecting the logs, but this seems to be the case with our setup.
