I now drilled two holes in the encasement of the WRAP, also have the
bottom "lifted" (put two pencils under it, so it gets air underneath
it). This seems to have done the trick, it does not freeze anymore, so
I am inclined to think that my freezes were indeed temperature

However I cannot imagine that it reached the critical 80 degrees
Celsius, the encasement never was more than hand-warm. But it all
makes sense: more CPU-load creates more heat, it's as simple as that.

Thanks for the information. There also was another problem, my Asus
P4P800 motherboard has an onboard NIC 3Com 940C (Gigabit). This one
stopped working reliably after about 1.5 years, often lost it's DHCP
lease (m0n0wall logged "device released, interface not found") and the
NIC simply froze for about 2 hours, then it "magically" submitted a
DHCP request, got served and worked for another e.g. 6 hours. Since I
disabled that NIC and replaced it with an Intel MT 1000, everything
works fine again.

I am considering to go back to 1.2b3, then I will loose the SNMP
reading of CPU-usage, ah well ...

Kind regards   Frederick
