I am experiencing the same problem in a cvpn 3060 only with webvpn service running. The concentrator suddenly hung up 2 days ago. Now, in the event log it keeps appearing this error.

I have version 4.7.2L installed.

Any ideas how to solve this problem?

thanks in advance.

I've searched bug toolkit and found "CSCsl27954 Bug Details". I upgraded the cvpn to version 4.7.2.P but this type of error

"11786 09/25/2008 16:12:41.510 SEV=4 HTTP/37 RPT=223 Closing socket 6 for invalid connection 0xDA204A4"

keeps appearing.

any ideas?
