[Asterisk-Users] What are these error messages in my logs?

[myotheremail at netacc.net]

Hello,
I am getting a bizzare amount of error messages in the log files.
The system seems to be running fine...no one is reporting any issues and all calls are coming and going.
System is showing higher than average memory usage.
eth0 is showing a high number of errors 

Running v1.1
Has happened on older versions and have been seeing this for quite some time but have just now asked if anyone knows what is going on.
Could not find anything in wiki about it.

Thanks for any comments.

debug below:
