WS-8-150-AC keeps rebooting

[vitell]

Hi all,

Got a problem with a WS-8-150-AC (running 1.5.14). Basically, it keeps rebooting somewhere between every half hour and hour. There doesn't seem to be any reason for this:
Memory usage looks OK (sits at around 44MB)
CPU usage looks OK (sits at around 10%)
Board temp - 40C
CPU temp - 60C
PHY temp - 60C
Fan working
Power consumption - 21W
SNMP/SMTP/SSH/IPv6/Discovery/Syslog/Auto backup/RADIUS/IGMP snooping - all disabled

What debugging can I do? Is there anything I should be looking at specifically?

Cheers,
Nicholas.

Nobody has any ideas? Ah well, I'll just bin it then.
