Summary0006286: Telnet Process Crashes Kernel
DescriptionI have a process running on a router (CentOS 6.3 stripped down) that telnets out to another server and reports stats every minute. The router has crashed a few times over the last month or 2, and the vmcore always says something like this:


      KERNEL: /usr/lib/debug/lib/modules/2.6.32-279.19.1.el6.x86_64/vmlinux
    DUMPFILE: /var/crash/127.0.0.1-2013-03-02-11:31:36/vmcore [PARTIAL DUMP]
        CPUS: 4
        DATE: Sat Mar 2 11:30:30 2013
      UPTIME: 3 days, 17:31:39
LOAD AVERAGE: 0.02, 0.01, 0.00
       TASKS: 140
    NODENAME: lateapex-gw
     RELEASE: 2.6.32-279.19.1.el6.x86_64
     VERSION: #1 SMP Wed Dec 19 07:05:20 UTC 2012
     MACHINE: x86_64 (1500 Mhz)
      MEMORY: 2 GB
       PANIC: "Oops: 0000 [#1] SMP " (check log for details)
         PID: 27004
     COMMAND: "telnet"
        TASK: ffff880037dc0040 [THREAD_INFO: ffff88007a10c000]
         CPU: 3
       STATE: TASK_RUNNING (PANIC)

Specifically it's always the command "telnet" that seems to do it. I can't tell if it's actually telnet doing it, or if telnet is tripping over something else.

I've cleaned the vmcores up, but if it happens again, I'll attach one to this report assuming it falls within your file size.
