I know these 1655MC's are pretty old, but for what I'm doing there should be
Please excuse me if I am bringing up an old issue. A quick search of the
archive didn't show me anything useful.
This is probably not a BIND issue, but I'd like to know if anyone has seen
this before. Perhaps point me in the right direction.
I have a dell 1655MC blade with the following:
Linux kernel 2.6.8
Tg3 NIC driver from Broadcom, compiled and installed as a module
IP Tables disabled
Nic is 1000fdx to the switch in the blade chassis
The name server runs just fine at around 100-200 DNS queries per second.
When the load reaches 300-500 qps, the network will preiodically diappear.
I don't mean drop, I mean disappear. It is very strange. When it goes, the
- No traffic is passed, TCP or UDP
- No errors occur
- Link status does not change, show up
- The OS thinks the user is still connected, even though the SSH traffic is
not passing (verified with KVM connection during an event)
- No errors on the interface
- No errors on the switch
The drop is for 30-60 seconds, then resumes.
Has anyone seen anything like this?
