I've been having problem with a Wrap.1C board haning after 4-5 days

Like you the board just locks up and refuses to respond to either
ethernet or serial connection but doesn't post any error messages
either to the Syslog or serial console.

However on the suggestion of a post here I tried disabling the Traffic
shaper and since I did that the board has managed a couple of weeks of
faultless operation (just like under v1.1).

Unfortunately I can't reliably reproduce the problem without just
leaving the board running for several days but I am pretty convinced
that something in the v1.2 traffic shaper (or maybe the rules built by
the v1.2 Shaper wizard) that is causing a serious problem with my Wrap
board (and possibly other people's).

So do you have Traffic Shaper enabled ? If so, do you still have the
problem with the Shaper disabled ?
