Ignore sigpipe is a configure option. Check the man/faq about webserver dying 
with no error.  Also try -t d and maybe -K? I'm OOO so can't really help more 
right now.

Subject: [Ntop] ntop web server stops responding

Hi All,

I see my ntop web server stop responding every few days (I really only 
check it once in the morning unless there is a problem). The process 
seems to keep running though the webserver is dead. I am running CentOS 
5.3 and I have seen there are redhat type issues in the man page 
suggesting "--disable-schedyield" and also I saw some google posts 
suggesting the use of "--ignore-sigpipe" (though this does not appear to 
be an ntop option).

I thought I also saw chatter about ntop crashing when being run on 
RHEL/CenOS with multiple monitored interfaces, but I am only monitoring 
one.

So is there a prevailing thought on troubleshooting this problem, or 
should I just try those two suggestions and see what mileage I get out 
of them?

Here is my current startup parameters:

ntop      1889     1  2 17:03 ?        00:00:11 /usr/local/bin/ntop -u 
ntop -o -m 192.168.1.0/24,x.xx.xx.xxx/25 -i eth2 -a 
/var/log/ntop/ntop.somewhere.com -w 0 -W 192.168.1.xxx:8443 -d

Thanks,
James
