Dnscache.db does seem to cause some issues. Do you recall how big yours was before you wiped it? I know there's a flag to disable lookups all together, but I wish there was a flag to disable the use of dnsCache.db. Winblows (and others) cache dns already - we don't need more than one cache.

I've also seen my share of the bad magic numbers. Search the list, there are different thoughts on the bad magic issue. Could you be out of memory - either total memory or per process memory? ________________________________ From: [email protected] [mailto:[email protected]] On Behalf Of Terry Martin Sent: Tuesday, April 14, 2009 1:59 PM To: [email protected] Subject: [Ntop] NTOP is crashing To all I am using NTOP on a CentOS server and it appears has been crashing when I am working in the throughput tables.
