Hi, all :
My user called Tom, and his vnc desktop suddenly did not work just now. Then I went to see the server log message , and found the following message:
kernel: Xvnc[2779]: segfault at 00000000008 rip 000000000077af44 rsp 00007fff5ee310c0 error 4 kernel: eclipse[25300]: segfault at 00000000008 rip 000003210cfbc6c rsp 00007fff470c66a0 error 4 gconfd( tom-2764): Gconf server is not in use , shutting down gconfd: Exitting ..
By the way, my server os is CentOS 5.3 x86_64 and kernel version is : 2.6.18-128.el5
It looks it is the eclipse tool problem which cause the kernel crash, isn't it ?
Partly correct. The kernel kills the program with SEGV, because the program has tried to do something it shouldn't do. That's why you see that segfault message in dmesg/log files. It is not an indication of kernel failure. It's an indication the kernel took action.
Could someone can give me some suggestion which can avoid that message happend again?
You need to figure out which program causes this error. You have both Xvnc and eclipse failures. It might be that when one of them segfaults, it brings down the other one too, as a segfault.
It's impossible to say exactly what the error is, just based on this information. The only thing which is clear, it's a user space error and not a kernel issue.
Btw. you're running on a very old CentOS base (5.3). I would first try to upgrade to at 5.5, and see if the error still is persistent. 5.3 has not received much love since 5.4 and 5.5 is released. Now all the focus is on getting 5.6 out the door too.
kind regards,
