-bash-3.2$ cat /etc/redhat-release
CentOS release 5.3 (Final)
-bash-3.2$ uname -r
2.6.18-164.2.1.el5.028stab066.10

rpm -qa|grep ^at
at-3.1.8-82.fc6

刚刚把系统升级到
# cat /etc/redhat-release
CentOS release 5.4 (Final)

#uname -a
Linux localhost 2.6.18-164.2.1.el5.028stab066.10 #1 SMP Sat Dec 12 18:52:53 MSK 2009 x86_64 x86_64 x86_64 GNU/Linux

环境都是在测试用的虚拟机上搞的，在多台机器上测试出来的结果相同。虚拟机不在同一个HOST上面。
有环境的兄弟们能否帮我验证下。谢谢
