Hi,
There's a broadcast storm & Sun boxes (a couple of Ultra 5s & two
E220Rs & an E250) on a LAN froze/semi-froze. By disconnecting
the Sun boxes from the LAN, they all boot up fine; after connecting
back, they froze; & defroze when the connection is removed
again. Netsfcreen firewalls on this same LAN are more resilient. I've
always thought that broadcast storm & the 'ping of death' could only
freeze/crash low end boxes like Sparcstations & Cisco boxes built in
early nineties but we're now seeing it with faster Sun boxes as well.
It's a broadcast storm because whenever the Cisco switch 29xx
LEDs blink very rapidly at the same time (I think this is indication
there's a broadcast storm - correct me if I'm wrong), it would
hang those Sun boxes within seconds. All the affected Sun boxes are
on Solaris 7 & the E250 which I'm the administrator, boots up fine when
the culprit devices (a pair of Layer 2 Netscreens) that's generating the
storm is isolated from the LAN - the Sun firewalls have now connected
back fine to that LAN. Not a duplicate address issue too.
Is there any patches recommended for Solaris 7 that could make the
Sun boxes more resilient to this?
For that E250 which I administer, the following messages appear on
the console once every few minutes when it hangs :
WARNING: ldterm: (ldtermrsrv/newmsg) out of blocks
WARNING: ldtermrsrv: out of blocks
WARNING: ldterm: (ldtermrsrv/newmsg) out of blocks
