Problem Description: 

1184046 On an SS10/SS20 with 4.1.3_U1/FSBE , if etherfind or snoop is
        started on le1, the le1 interface hangs and needs to be reset by
        an ifconfig or a reboot.

(from 101954-05) 

1177296 The ethernet interface hangs when transfering a large file (rdump ,
        ftp, rcp or cp from NFS) but only when using AUI. When using TP,
        it works fine .The problem  happens on SS5 or MACIO based systems.

(from 101954-04)

1145294	Problem is seen on active networks where the network interface on
	Classic's, LX's, Sparcstations 5 and 20 (based on MACIO) may hang
	and ignore incoming ethernet packets after receipt of a giant packet
	that is greater than 4096 bytes. This fix will detect this condition
	and reset the ethernet interface to prevent the interface from hanging.

1163300	le0 ethernet interface suddenly freezes during rdump

1170392	Under heavy loads (as a result of heavy network activity or 
	disk activity), SS10 hard hangs with le0:memory errors.
