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.

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,
