(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.
