ls -l замораживает терминал локально и удаленно

Я читал другие темы SF относительно ls не возвращая результаты или замораживая и останавливая терминальные сессии, и кажется, что они обычно виноваты в проблемах сети. Моя проблема, однако, возникает как через удаленные сеансы SSH, так и в том случае, если я физически на самом сервере...

Я только что установил CentOS 5.4 на один из наших серверов. Я настраиваю некоторые скрипты rdiff-backup, и когда я скачал librsync и удалил его, вот тогда я и увидел странное поведение с ls -l,

wget http://sourceforge.net/projects/librsync/files/librsync/0.9.7/librsync-0.9.7.tar.gz/download /tmp

cd /tmp

tar -xzf librsync-0.9.7.tar.gz

Достаточно просто. Для просмотра файлов в этом каталоге я сделал это:

ls

Результаты:

librsync-0.9.7  librsync-0.9.7.tar.gz

Теперь, если я ls -lМой терминал зависает. Я должен повторить ssh, чтобы продолжать идти. После прочтения темы SF я подумал, что это связано с сетью.

Поэтому я был крайне удивлен, когда сел за сам сервер и увидел, что происходит то же самое... Так что, очевидно, это не проблема сети.

Даже если я ls /tmp/librsync-0.9.7мой терминал зависает точно так же...

Затем я сделал стрейс и получил это (предупреждение: стена текста идет....):

strace ls -l /tmp

ls -l > out.txt 2> err.txt в результате пустые файлы out.txt и err.txt.

ls -n ДЕЙСТВИТЕЛЬНО вернул правильные результаты. Так что же такого в GID и UID, с которыми у него проблемы? Это проблема LDAP, как сказал Слобо? Почему мой сервер пытается связаться с нашим сервером LDAP, когда я перечисляю файлы?
