Hello!
I got silent data corruption when transferring data via em(4) interface on
10.2-STABLE r286912.
1. I got broken large file transferred via ftp (MD5 checksum mismatched);
2. I got disconnects when transferring large data via ssh with messages:
Corrupted MAC on input.
Disconnecting: Packet corrupt
Problem occurs only after few hours of uptime. Immediately after reboot I
transferred same file via ftp without any errors.
I tried to use:
- em0 and em2 interfaces in link aggregation
- em1 as "clean" interface
But I got same problem in both cases.
Also one time when transferring file I got this messages:
em0: Interface stopped DISTRIBUTING, possible flapping
em0: Watchdog timeout -- resetting
em2: Interface stopped DISTRIBUTING, possible flapping
em2: Watchdog timeout -- resetting
netstat -in does not see any problems:

Network adapters is build in to the Sun Fire X4100 mother board:
em0 at pci0:1:1:0: class=0x020000 card=0x10118086 chip=0x10108086 rev=0x03
hdr=0x00
vendor = 'Intel Corporation'
device = '82546EB Gigabit Ethernet Controller (Copper)'
class = network
subclass = ethernet
TCP_OFFLOAD disabled in kernel's config.
Any ideas?

You can disable on the interface with '-tso'. Cheers, Hiren -------------- next part -------------- A non-text attachment was scrubbed...
