That looks like myGlobals is corrupted... don't see how it could be, but...
 
can you do this too
 
(gdb) print myGlobals
(gdb) print myGlobals.runningPref
(gdb) print *(myGlobals.runningPref)

Subject: [Ntop] Ntop crahses at startup

Hello,

I have just installed ntop this morning and it worked all fine until I created a netflow interface using the web interface. When I did this ntop crashed.

Until then, it has been impossible to start ntop correctly again. Here is what it does at startup :

I compiled ntop again, I deleted all the plugins, libraries and other stuff installed by the make install and did a make clean/make install again. I rmmod'ed af_packet and tried ntop again and finally I rebooted the host and tried again... nothing worked. Ntop crash again and again at startup... I tried to disable the multi-threading :

Does anybody have a clue of what's happening ?
