[ILUG] problems running nessus

[Owen Connolly]

Well it seems, from what you're saying, that one or more plugins are 
causing nessusd to segfault.  You'll probably find, if that's the case, 
that it's affecting more that you and you'll probably get better 
information on the nessus.org mailing lists. 

Apart from that, I'd suggest downloading the plugins again and copying 
them out to a temporary directory. Then add them in blocks of 10 or 20 
at a time, until it happens, take the block out again and add them 
singly until it craps out again, then report the issue on the 
plugin-writers list.

I know this is a tedious way of doing things, but it's also bloody 
effective... ;-)

Cheers,
