Syslog Erros !!

I had a user server connectivity issue being raised on one of my HP box some time back.
After checking the logs I could see some erros as below:

I am not really sure what is this about.
I have checked the connectiviy, CPU usage and everything seems to be normal.

Kindly provide your inputs if this is a serious issue.

This clearly tells that you've passed an invalid arg to this function.

Generally, is your code checking for error returns from C funtions properly? If not, that might lead to subsequent calls being made erroneously.
