Known Affected Releases
Symptoms: When you attempt to browse to a WebVPN portal you only see a blank page. The router does not send the browser a certificate and the portal login page is not displayed. The command <CmdBold>debug webvpn sdps<noCmdBold> logs the following error message: WV-SDPS: Sev 4:sslvpn_tcp_read_notify(),line 1569:No to notify read: already queued 004549: Conditions: The symptom is observed when the SSLVPN process is waiting for an HTTP REQUEST from a client on the port configured using the <CmdBold>http-redirect <port no><noCmdBold> command but the process does not wake up. This can happen because of an unexpected IPC message to the SSLVPN process by another IOS process.
