September 29, 200817 yr Hi all, What is it in syslog? (code bellow) Sep 29 19:21:46 Tower kernel: <unknown>: hw csum failure.

September 30, 200817 yr I don't want to extrapolate too far, from just an excerpt of the syslog. On the surface, it appears to be an internal error ('hardware checksum error') during the operation of the sky2 network driver, but that can be misleading. Debugging from such little scraps can be a waste of time sometimes, since you don't really know for sure how we got here. All we do know is that the error was serious enough to produce a trace, and you probably need to reboot, to bring the system and drivers back to a stable state. A few questions: Have you seen this before? Was it at or near startup? Was there a particular operation in progress? Were there any network transfers in progress (as far as you know)? There may not be much anyone can do to help you. If it is a one time thing, then don't do anything except increasing your monitoring of the system. If it repeats, then you should try to determine what operations and/or conditions are common to these events. Get syslogs each time.
September 30, 200817 yr Author I am do backup data from stations to server. No transfer errors found. I am do not any change in NIC or NIC driver. I do not know why this error is create. I will watch this error and capture syslog again.
