iperf 시험 중 발생한 Error 입니다..
안녕하세요 ~
하나의 Server에 Ethernet Interface를 2개 탑재하고
양쪽에 PC Client를 연결한 후에 한쪽에는 iperf Server를
또 다른 한 쪽에는 iperf Client를 설치하고 data 전송을 시작했습니다.
Session을 250개까지 연결해서 bandwidth는 1MB로 설정하고
시험을 해보려 했는데,,session이 100개정도 만들어질 때쯤 아래와 같은
문제가 발생하네요,,
몇 차례 해봤는데,, 같은 error가 보이는 것 같아서요.
고수 분들의 조언과,,또 경험자 분들의 조언을 듣고 싶어 글을 올립니다.
그럼...부탁드리며, 미리 감사드립니다. ^^

LOCKUP ???
위의 Error message 중에서 아래 message가 가장 눈에 띄네요..
뭔가 SMP에 문제가 있는 걸까요?

위의 Message 중에서요 ~
"BUG:"라고 나온건 Kernel이 만든 Message이겠죠?
BUG라고 한 말이 의미하는 건 뭘까요?
Kernel이 이러한 문제를 BUG라고 detect했다는 뜻일까요?
