   The only times I have had that kind of trouble is when there was   
   packetloss on the connection between two sites.  A good example is   
   recently I had trouble maintaining VPN links from home.  I found that my   
   cable modem would drop large packets.  As the size of a packet   
   increased, it's likelihood of it being lost increased in this case.   
   When doing a ping with the default 32 bytes the packetloss was almost   
   0%.  At the maximum ethernet packet size (ping with 1472bytes) the loss   
   was often nearly 90%.  The cable company tech came out, we hooked up the   
   modem to the pedestal out on the street and found the same trouble there   
   so he booked a call to have network maintenance come out and fix the   
   amplifiers in the area.  A week later and now everything is great again.   
     I get no packetloss with large packet sizes and my VPN connections are   
   solid again.   
      
   It's possible you have some lower level problem with your internet   
   connections.  Packetloss is an enemy to a stable VPN connection.
