Script Engine scanning getting stuck in loop

Hi All, I've run into an issue with the script engine while scanning a host, it gets stuck in an infinite loop. Running nmap-4.53 on Centos5. I've compiled it from source with default options. # nmap -A -v -p1-65535 -vvv HOSTNAME.COM | tee nmap.log At a certain point during the scanning it just begins to loop: [.] NSOCK (485.4790s) nsock_loop() started (timeout=50ms). 0 events pending NSOCK (485.4790s) nsock_loop() started (timeout=50ms). 0 events pending NSOCK (485.4790s) nsock_loop() started (timeout=50ms). 0 events pending Stats: 0:08:05 elapsed; 0 hosts completed (1 up), 1 undergoing Script Scan Active NSE scripts: 102 SCRIPT ENGINE Timing: About 17.74% done; ETC: 23:15 (0:03:14 remaining) NSOCK (485.4800s) nsock_loop() started (timeout=50ms). 0 events pending NSOCK (485.4800s) nsock_loop() started (timeout=50ms). 0 events pending NSOCK (485.4800s) nsock_loop() started (timeout=50ms). 0 events pending [.] SCRIPT ENGINE Timing: About 17.74% done; ETC: 23:18 (0:05:56 remaining) ^C While this is happening nmap seems to be continually pouring out the above `0 events pending` line. After the 5 minute test above I had a 100 000 line logfile. I trimmed it and attached it to this mail: $ cat nmap.log | grep --context=10 -v "nsock_loop() started (timeout=50ms). 0 events pending" >> nmap2.log Let me know if I can provide more info. Cheers, Alex
