I got yet another clean 2.0.33, applied 2.0.34pre3, tcpdebug and the
print_eip stuff.
Then I stressed two of my servers with simultaneous www/ftp/smtp connects
and disconnects. After about half an hour (moderate swapping) I got an Oops
and shortly after that both machines locked up completely.
I bet that anybody out there can reproduce that. I easily can (and I
guess I can crash all my 2.0.3[23] servers). `Process' is always
httpd (apache 1.2.4).
