Why does this happen?

Hello all,
    I left the kdc server running for the whole night, and this morning I found the kdc server has already been down. The reason for this is that the /var/log/krb5kdc.log file beacame too large, over 2G. I deleted it and started the server again, and the log file was like this:
Oct 19 10:54:29 gdnode001 krb5kdc[8478](info): setting up network...

    For some reason, the kdc server(192.168.100.100) failed to find the client test/admin at stg.com , then the log message " DISPATCH: repeated (retransmitted?) request from 192.168.100.100, resending previous response " was generated every second till the log file became over large.
    Could someone help me to avoid this? Thank you!
