Fixed In:

Opened: Jun 05, 2014
Severity: 3-Major

Symptoms

tmm may core when OneConnect is configured on the virtual. The connection is put in pass-through by the client and disconnected. At this point in passthru mode when the server processes ingress data, it accesses free'd memory location leading to core.

Impact

Traffic disrupted while tmm restarts.

Conditions

OneConnect is configured on virtual. WebSockets are in use, the client hence puts connection in passthrough, post which we have ingress data on server side.

Workaround

None.

Fix Information

WebSockets and the HTTP CONNECT method now work with OneConnect.
