Find command not working in CentOS based distribution, strange bug or?

Question

linux

The find command does not work in XenServer (as we know it is a CentOS 5-based distribution), a strange bug or something else?
The server has not been updated, and third-party utilities except (mc, vim, nmap) because the base repository is disabled by default. And dear Tobias, the citrix forum does not recommend this:

"Thrid party applications are not supported on XenServer. Doing so could void any support."

Everything worked, now it doesn't work.
Directly specifying the path also displays an error that the file or directory does not exist.

# find .

Other information:

#cat /etc/redhat-release

#ls -la /usr/bin/find
-rwxr-xr-x 1 root root 155256 Врс  3  2009 /usr/bin/find

#yum list installed | grep find
findutils.x86_64                      1:4.2.27-6.el5                   installed

#yum reinstall findutils --enablerepo=base
Переустанавливает с репозитория но проблему не решает.

#ps aux | grep find
Зависших процессов нет

#find --version
GNU find version 4.2.27
Features enabled: D_TYPE O_NOFOLLOW(enabled) LEAF_OPTIMISATION SELINUX
