I'm having the same problem. In my investigation it seems to happen when the
client renews the IKE lease (every 120 seconds). This only seems to effect
remote control programs like Term Services and PC anywhere. They will
completely loose connection to the remote host. E-mail clients an other
applications seem to tolerate the lease renewal drops. You can get up to 10
dropped pings during this process.

I tried changing the client SA life (in seconds), phase one and two, to a
much higher value (looks like the max is 28800 seconds (8 hours)). The GTA
suggested value is 120 seconds. This made the lease much longer (visible in
GBAdmin | System Activity | Active VPNs) and therefore reduced the number of
times it had to be renewed (causing the network drop).

There may be security implications of having longer leases though.
Connection hi-jacking, etc. And this extended lease also consumes a license
until it expires. Even if the client computer has been shut off.

Yup. I've seen the same thing since upgrading to the latest client
version. A number of other folks here have mentioned seeing it. No
particular hints as far as a workaround.  You probably should
call GTA's tech support and log a call.
