Our customer is using DECbridge 520 v.1.2 in dual homing
configuration.
Twice this week, one of the DECbridge hung without any
external indication (Online & forwarding LEDs were ON)
but no traffic was anymore forwarded and you didn't get
any answer from this DB520 using DECmcc.
A power off/on done by the customer restarted the DECbridge 520.
Next time, we'll disconnect/connect Ethernet and FDDI cables
to check what will happen.
How could this happen to the DECbridge ?
I am waiting for the diagnostic block dump, is there any useful
information in it ?

Customer's informations are sometimes measleading.
In fact, the DECbridge which reset itself is a DECbridge 620 v.1.2
directly connected to the dual ring.
Sometimes, it hangs or reset. Problem seems hardware since only
this one through the nineteen of them is impacted.
Counters only displayed "unsolicited reset". I think about a AP2
module problem but I would like to know if somebody could confirm
from this beginning of NVRAM errlog (diagnostic block), below.
