That sounds like poor power management (inadequate surge suppression) on
the GB-1000.

GTA may want to start performing "SWAC" AND "HIPOT" testing on future
designs.

In the interim, anyone having similar problems can probably get a surge
suppression device (look for one that employs movistors and transorbs)
that will eliminate any possibility of spurious energy (surges and
associated harmonics) from impacting the device. If other devices on
this strip were impacted, then another possibility would be that the
"strip" in question may be tripping, thus mimicking a power failure.

I would wager it is surges causing these "hiccups".

Just a thought.

Subject: [gb-users] GB-1000 lockups solved

I posted a message about a problem I was having with my GB-1000 locking
up on me (the original message is pasted at the bottom of this one).
Just wanted to follow up with the solution. I have a APC UPS 2200XL with
two power strip (surge suppressors) attached to it (Belkin brand). I
have several servers and switches and the GB-1000 attached to one of the
power strips. The lockups on the GB-1000 were occurring every time the
UPS ran a self test (which I hade scheduled for 6:00am every Sunday).
Sometimes the GB-1000 would stop responding for a little time and then
come back to life, other times it would have to be rebooted. Once I
found out that this was happening because of the UP self tests, I tried
some tests. The other devices attached to this power strip were not
affected at all by the self test. When I moved the GB-1000 power cord
from the power strip to a dedicated plug on the back of the UPS, the
problem was solved.

I have a GB1000 that worked fine for several years in a previous
location. I have moved it to a new network and reconfigured it. Now it
is locking up occasionally. It is now connected (on the external
interface) to a network that is shared by other companies. I have 6 IP's
that I can use (which are not all in a continues block) (i.e. EXT
network is XXX.YYY.ZZZ.128 SM 255.255.255.224). I have been given .139,
.142, .143, .144, .156, and .157 IP's in the XXX.YYY.ZZZ.128 network to
work with. The EXT interface is on XXX.YYY.ZZZ.139. I have created alias
for the other IP's that I have been given. I have a Protected network of
10.10.10.0 SM 255.255.252.0. The Protected network interface is on
10.10.10.1. A verify configuration comes back without any errors.

Occasionally the GB1000 will lock up. This happens randomly, but seems
like it is about 2 - 3 weeks between lockups.

When the GB1000 locks up:
1) It will not respond to ping on any of the external IP's aliased to
the external interface
2) It will not respond to ping on the protected network interface
3) It will not respond on the console interface
4) It doesn't pass any traffic from the external to the internal
interface
5) I have logging turned on and no errors show up in the log, the GB1000
just stops sending any messages to the logging server when it locks up
6) The power light on the front is glowing red
7) The ext and protected interface lights on the front show solid amber
and flashing green (as though it thinks it is sending traffic)
8) The ext and protected interface lights on the cable jacks on the back
show solid amber and flashing green (as though it thinks it is sending
traffic)

If I cycle the power on the GB1000, it comes back up without errors and
works fine (including sending log messages). Any ideas?
