[Openswan Users] L2TP session zombied?

[James]

Hi guys i was wondering if any of you experienced something like this in 
your logs

Mar 6 14:34:47 tunnel l2tpd[26501]: get_call:can't find tunnel 21195
Mar 6 14:34:47 tunnel l2tpd[26501]: network_thread: unable to find call
or tunn
el to handle packet. call = 13304, tunnel = 21195 Dumping.

Mar 6 14:34:47 tunnel l2tpd[26501]: network_thread: unable to find call
or tunn

Mar 6 14:34:48 tunnel l2tpd[26501]: get_call:can't find tunnel 21195
Mar 6 14:34:48 tunnel l2tpd[26501]: network_thread: unable to find call
or tunn


I had a user say that they kept getting disconnected every couple 
minutes. They're trying to VPN from overseas and i'm thinking maybe 
there's some delay that's causing some problems.

Maybe the ipsec session timesout but the l2tp session stays alive?
i dunno that's just my shot in the dark.

Had to restart l2tp to get it back to normal for the user.

TIA
