I've got an issue that is serving to constantly frustrate me and make my LMCE setup unusable. I'm hoping someone may be able to help me. The issue that I'm seeing is that when I have MDs running, at some point in time the internal network fails. By fails, I mean I can't ping any machine from the core, and vice versa. The MDs freeze, and the windows PCs indicate limited (non-DHCP access) My squeezebox goes blank, indicating loss of communications to the server. However, there are no indications on the core that anything is amiss. ifconfig indicates that the network connection is active, though RX and TX packets count up very slowly and erratically). I've never seen this issue happen when I don't have MDs running. The outside NIC is fine, i.e. I can access the internet from the core. Shutting off any running MDs immediately corrects the problem and the network returns to normal (ie. windows PCs are routed to the internet, squeezebox works).
My setup is:
Hybrid: Intel S5000PSL
1 Abit AN-M2HD
1 ASROCK ALiveNF7G-FullHD R3.0
I've tried the following:
1) Updated the kernel to 2.6.27 to try the new e1000e driver for the onboard intel gigabit lan
2) Swapped out network cables/ethernet switch
3) Tried each MD singly and together
4) Added D-link network card to core to test new hardware/driver
5) Tried 64 and 32 bit versions of LMCE.
Still, in anywhere from 2 to 72 hours, the problem recurs. Has anyone seen this before? Anybody have any ideas of where to look to troubleshoot? Any help would be greatly appreciated.
