telnet service restart. Why??

zgzjcy

在RedHat Linux8.0下, 不知为何出现无法telnet?(ftp可以)
但在/var/log/messages中却有如下信息:
1.Deactivating service telnet due to excessive in
coming connections. Restarting in 30 seconds.
2.messages中记录的时间已乱套:
  Mar 23 17:29:35 pts -- aa[32682]: LOGIN ON pts/3 BY aa FROM ..
  Mar 23 17:29:32 pts login(pam_unix)[32736]: session opened for ..
  但系统时间却是Mar 24 , 以上记录是24号telnet时记下来的
