I'm pretty new to kernel programming and don't really know how to read the kernel crash log and was hoping someone would help me. The echo server crashes so randomly that it is hard to pinpoint where it is crashing. Most of the time it works for about 2 hours(about 20-30 iperf commands) then the kernel freezes and crashes and needs a reboot. I caught the crash once and it seemed to crash in the middle of an iperf command. > >Here is the version of linux I am running. > Linux 5NetSim08 2.6.35-22-generic #35-Ubuntu SMP Sat Oct 16 20:36:48 UTC 2010 i686 GNU/Linux Are you sure?

Are you running another kernel as a user-mode process? -- Tim Roberts, timr@probo.com Providenza & Boekelheide, Inc.
