Hi,
We are encountering this issue with one of our production web servers. I am not sure what is the exact event that triggers the crash, but it looks like something to do with a bad tcp packet ? Hardware vendor: Vmware machine (runs with about 20 more machines, only this ones has this issue). Kernel version: 2.6.18-238.9.1.el5 x86_64 x86_64 centos-release-5-7.el5.centos Console screenshot - http://desmond.imageshack.us/Himg696/scaled.php?server=696&filename=kernelpanic.png&res=medium Routing table that is running on that server - Routing scripts because we have two networks and two DG (the real ip addresses replaced for the example) |

Hi,
Please note - http://lxr.linux.no/#linux+v2.6.32/n.../route.c#L1945 See lines 2108, 2146, 2254 I was able to reproduce the "martian source" error, but was not able to generate a kernel error. |

Your last link is bad. That's a very old kernel-2.6.18-238.9.1.el5. What happens with a "yum update" to get to the current/supported release, including 2.6.18-274.18.1.el5?

Hi Phil,
I've upgraded the kernel from 2.6.18-238.9.1.el5, to 2.6.18-274.18.1.el5 So far the system is stable. Will update this post if the issue will occur again. Eli. |

Staying up to date is nearly always a good idea. Please let us know how it goes so the thread can be marked [SOLVED].

UPDATE -
I've just found there is a duplicate IP, on my DataCenter (not from my servers, it seems like someone over there is using one of my ips). I turned off all the interfaces, and pinged all the ips on that server, one of them answered a ping (when the interface was down !). I think it can cause the kernel panic error, when they are both answering tcp traffic (my server and the other machine) at the same time. In the meantime, I turned off the interface on my server that uses that ip so all the rest could work, I will update the post when I will be sure the problem was solved. Eli. |
