仲村さん、はじめまして。
こんにちは、小島です。

70個 Include すると起こります。69個までは大丈夫でした。
１つの Include のファイルは 53行ぐらいですが設定を20行ぐらい
に情報量を削ると Include の行は増やせます。
70個目を Include せずに直接 httpd.conf に追加しても同じ症状が
発生しました。
似たような環境で
FreeBSD 4.10R + Apache/1.3.33 Ben-SSL/1.55 (Unix) mod_jk
mod_layout/3.2.1 DAV/1.0.3
という環境があるのですがこちらは Include 数が増えても大丈夫です。
FreeBSD 6.1R のほうを Apache-SSL 1.3.34 から Apache-SSL 1.3.33 に
変更しても症状は改善しませんでした。

ありがとうございます。
make CFLAGS="-g -O0"付きで Apache をコンパイルして以下（文末）
のように gdb コマンドを実行してみました。何か最後に出たのですが
自分では意味がわかりませんでした。
truss -o /tmp/httpsd.truss /usr/local/apache/bin/httpsd
としたところ、最後は以下のようになっていました。
「xxxxx1」は Include 行の一番最初で「xxxxx2」は 2行目の
Include 行のログファイルの指定にあたります。
open("/usr/local/apache/logs/xxxxx2/access_log.xxxxx2",0x209,0644) = 5
(0x5)
fcntl(5,F_DUPFD,0xf) = 200 (0xc8)
close(5) = 0 (0x0)
fcntl(200,F_SETFD,0x1) = 0 (0x0)
open("/usr/local/apache/logs/xxxxx2/access_log.xxxxx2",0x209,0644) = 5
(0x5)
fcntl(5,F_DUPFD,0xf) = 201 (0xc9)
close(5) = 0 (0x0)
fcntl(201,F_SETFD,0x1)
open("/usr/local/apache/logs/xxxxx1/access_log.xxxxx1",0x209,0644) = 5
(0x5)
fcntl(5,F_DUPFD,0xf) = 202 (0xca)
close(5) = 0 (0x0)
fcntl(202,F_SETFD,0x1) = 0 (0x0)
break(0x844b000) = 0 (0x0)
open("/usr/local/apache/logs/xxxxx1/access_log.xxxxx1",0x209,0644) = 5
(0x5)
fcntl(5,F_DUPFD,0xf) = 203 (0xcb)
close(5) = 0 (0x0)
fcntl(203,F_SETFD,0x1) = 0 (0x0)
chdir("/") = 0 (0x0)
fork() = 4068 (0xfe4)
exit(0x0)
process exit, rval = 0

原因を調べている際に手元にある Apacheクックブックという本に
「mod_vhost_alias」の記載がありました。できれば避けたいのですが解決でき
ない場合は、代替方法として真剣に取り組まなければいけないかもしれません・・
