VPN Conncection between 3030 and Client freeze

We have sometimes the problem that a good working connection after a periode of time (for example 2 houres) freeze. The connection was not terminated but you are no more able to work on this connection.(No or only some data pass the Tunnel) Not even a ping to an internal maschine is possible. When you discconect, you are immediate able to connect again and continue work. Did anyone have the same problem or an idea what goes wrong here ?

On two of four such connections I find the following in the log :

"IKE AM FSM error history (P1 struct &0x7379570):

[20, 65535], [9, 78], [9, 32], [9, 65535]"


"Header invalid, missing SA payload! (next payload = 8)"

Is there a causal connection to our problem ?

Thanks for answer !

Re: VPN Conncection between 3030 and Client freeze

Having the same issue here. Using latest clients on both sides. I have also noticed that if you wait long enough that it sometimes comes back.

I have also noticed that pulling a lot of data at once can instigate this activity.

What I've seen has actually happened as early as 5-15 minutes as well.

Sorry I can't be of some help but I'm defintely feeling your pain.
