I just upgraded to Nessus 2.2.4 but am having some problems with it.
The master nessusd dies completely from time to time. That is all the
detail I have so I'll talk about the second problem. A child nessusd
process dumps core with the os_fingerprint.nasl plugin. I have copied
the gdb backtrace below. I'm not sure what to make of the file size
message since ulimit shows that it is unlimited.
I have version 1.108 of the os_fingerprint.nasl plugin and did a fresh
plugin download this morning. Nessus is running on a Red Hat AS 2.1
system. I can reproduce the problem at will.
