[Ntop] Ntop 3.3 on FC4 or FC5 will crash after a while (10min to XXdays)

[Gary Gatten]

Don't know if it will help in your case, but the dnsCache.db file seems
to cause me trouble when it gets "big".  Stop nTop, delete that file,
and fire it up again.  Maybe it will help - if not you didn't really
hurt anything.

Ntop is a great tool. I use to have the 3.2 version
installed from a RPM on a Fedora 4 machine and that
one use to be kind of stable.

Lately I got the latest stable version from
http://downloads.sourceforge.net/ntop/ntop-3.3.tar.gz
and compiled that on Fedora 5 and Fedora 4 because I
found no RPM available. All dependencies solved and it
did compiled OK.

I start Ntop with a command like:
ntop -u ntop -i eth1 --daemon --use-syslog=daemon
--no-promiscuous --no-fc
or
ntop -u ntop -i eth1 --use-syslog=daemon
--no-promiscuous  --no-fc &

Unfortunatelly it will stay up for a while (10 min to
xx days) and then will crash with an error similar to:

FC4 crash

Any Ideas?

Also 3.3 does look great but is slow over a satellite
connection compared to 3.2.
