Hi all,
I'm experiencing a problem with a GB-1000 3.2.1s. Anybody else?
Here's the problem illustrated. When the GnatBox is rebooted with large
amounts of traffic going through it hangs.
Here is the sequence:
A) Prior to reboot a large volume of traffic must be flowing through the
GnatBox.
B) Reboot the GnatBox.
C) Watch the console screen during reboot. (This is where the problem is
evident).
1) The network components are loaded (NIC drivers, IP address etc)
2) There is a default BLOCK EVERYTHING rule that is loaded PRIOR to
the customer created rule base.
3) Once the default BLOCK EVERYTHING rule is in place the GnatBox
begins frantically blocking the large volume of traffic that has been
flowing through it (to the exclusion of everything else). You can see it
doing this in the serial console. Screens and screens go by with blocked
traffic logs.
4) The GnatBox NEVER gets to the point where it loads the customer
created rule base. It is using all of it's CPU cycles to block traffic.
5) It will remain in this state until the network cables are
physically unplugged (or the traffic is caused to subside in some other
fashion).
6) Once this is done then you can see the GnatBox (through the
consol serial connection) load the customer created rule base and then it's
fine.
Thanks,
