I installed apache 1.0.5 with a patch that BSDI sent me. But the problem seems
to be not with apache itself but with "select" system call which can't handle
mode than 256 file descriptors in fd_set. And since apache opens 2 files for
every virtual host this number goes over 256 when you have over 124 virtual
hosts (or so). When logging transaction apache calls gethostbyaddr to get a
host name of the remote host. Gethostbyaddr creates a socket and calls select
to wait for an answer. And since that socket file descriptor is larger than 256
select returns an error "Invalid argument".
