Error logs from Apache:

[Mon Dec 10 00:16:39 2012] [error] [client 172.22.150.44] File does not exist: C:/Program Files/Apache Group/Apache2/favicon.ico
[Mon Dec 10 00:16:47 2012] [error] [client 172.22.150.44] File does not exist: C:/Program Files/Apache Group/Apache2/favicon.ico

From the webagent logs, i understand that the communication was forcibly closed by the Policy Server (remote Host). But i could not see any errors in the smps.logs.

Could someone please explain what is SMINPUTFILTER, and subsequent errors mean. And why does it close the connection and stop the LLAWP abruptly.

What does these two lines in the logs actually say\mean.

Though i have resolved the issue by stopping the LLAWP Process and restarting the apache. I would like to know why this happens and what would be the nearest cause, so that i fix this permanently.

Thanks.

Awaiting your answers and reply.
