It was posted here that it could be a DoS attack using the latest exploit.
I patched using the patch to prevent that exploit. I tried the exploit on
the patched box, and of course the exploit did not work. The crashes
continued however. I then patched both machines to ac5, and the crashes
still continue.
Machines are:
RH5.2
Running BIND
MD RAID1
Other than that, their is nothing special about these boxes. All the
RH5.2 updates have been installed. What can I do to further narrow down
the source of the problem?
