Dear All, I selected CentOS5 in my works and installed them in two DELL PowerEdge1950. However, a trouble blocked me during the machines run after two days. The machines crashed and the syslog said it got the following messages: ------------------ part dump of /var/log/messages ---------------------- .....

[http_cap:12228] ............. ----------------------------------------------------------------------------------- I choose CentOS because I believe it is the most stable OS in commodity machines. But I don't know how to do when facing the trouble. The difference lies in that I patched a PF_RING patch in original kernel and recompiled the kernel to run my machines. I wonder whether the patched kernel crashes the CentOS because PF_RING automatically downloads the kernel codes from www.kernel.org, but not the one from www.centos.org? Or, the centOS holds the bugs in its distribution? Hope somebody can given me some advices. Thanks in advance. Best Regards, Ian

google said that is a bug of kernel in network driver. And, someone seems to present a patch to fix the bug, however I would like to know whether it can work from others' works becuause reinstalling a new kernel may let us cost a lot.

BTW, the patched kernel by PF_RING is version 2.6.25.3.

We stopped using Dell machines some time ago. For some reason there reliability has been steadily falling.

I have turn back to original CentOS kernel, and then restart my program. In other words, my program run without PF_RING. By now, nothing happens. Therefore, it seems the bug results from PF_RING patch. Thanks for your help.
