    Today we were using nmap to scan our network and when we scanned our
    Tru64 machines, telnet and ftp froze and timed out. We could not make
    any connections to those ports and existing connections froze. New
    connections were denied for about a minute after the scan was finished.
    I've checked with Compaq and on Securityfocus and neither place has any
    knowledge of this. 
    
    We are running Tru64 Unix 4.0D patch kit 3 on Alpha 4100's and 8400's.
    The nmap command line that was used is:
    nmap -T Polite -O -p 23,139 -oM /tmp/lst 'xxx.xxx.16-44.*'
