From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705; .NET CLR 1.1.4322) Description of problem: When running the kernel-2.4.21-15.ELsmp kernel on a Dell PowerEdge 4600, the gigabit tg3 interface drops about 5-7% of packets. I ran a ping -f from two machines connected via CAT5 crossover to verify. When using the 9.0.3 release of the 2.4.21 kernel, there are no problems. Version-Release number of selected component (if applicable): kernel-2.4.21-15.EL How reproducible: Always Steps to Reproduce: 1. Run kernel-2.4.21-15.ELsmp 2. ping -f <machine over eth1> 3. See 5-7% dropped packets Actual Results: 5-7% dropped packets Expected Results: 0% dropped packets Additional info:
Do you see error such as: Jun 3 11:00:20 os-db01 kernel: tg3: eth0: Link is down. Jun 3 11:00:22 os-db01 kernel: tg3: eth0: Link is up at 1000 Mbps, full duplex. In the output of dmesg? Are you running Oracle on this machine while doing your tests? If so, it could be a duplicate of bug #123695
Yes, in dmesg,/var/log/messages -- and no, we are not running Oracle, only Apache, MySQL, and Postgres. I believe the newest kernel update has resolved this problem, as on one of the machines, I am not noticing any more dropped packets.
