[Openswan Users] Strange error:

[cngovanduc at gmail.com]

Hi list,

  Lately I've seen those messages appears in the log:

ERROR: asynchronous network error report on eth0 (sport=4500) for message to
x.x.x.230 port 60912, complainant y.y.y.163: Message too long [errno 90,
origin ICMP type 3 code 4 (not authenticated)]

  Any idea what might cause this?

Cheers,
Christophe
