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: Name Mtu Network Address Ipkts Ierrs Idrop Opkts Oerrs Coll em0 1500 <Link#1> 00:14:4f:01:3f:7a 6689452 0 0 146720 0 0 em1 1500 <Link#2> 00:14:4f:01:3f:7b 5732168 0 0 2865912 0 0 em2 1500 <Link#3> 00:14:4f:01:3f:7c 501817 0 0 3392333 0 0 Network adapters is build in to the Sun Fire X4100 mother board: em0@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.
