Re: Assertion failure in nsock_core

[Joao Correa <joao () livewire com br>]

I'm going through a similar problem here. I've tested it on two
different systems:

Ubuntu Linux:
==============================

lvwr@ubuntu:~$ nmap scanme.nmap.com -p80

Starting Nmap 4.90RC2 ( http://nmap.org ) at 2009-07-07 07:57 BRT
nmap: nsock_core.c:139: socket_count_zero: Assertion
`iod->events_pending == 1' failed.
Aborted
lvwr@ubuntu:~$ uname -rv
2.6.28-13-generic #45-Ubuntu SMP Tue Jun 30 19:49:51 UTC 2009

==============================

Mac OS X 10.5:
==============================
livewire:nmap joao$ nmap scanme.nmap.com -p80

Starting Nmap 4.90RC2 ( http://nmap.org ) at 2009-07-13 13:29 BRT
Assertion failed: (iod->events_pending == 1), function
socket_count_zero, file nsock_core.c, line 139.
Abort trap
livewire:nmap joao$ uname -rv
