[sctp-dev] Linux Kernel Failure (Fedora) and sctp close()

[Danny]

Hi,

Since i use the lksctp lib and the SCTP API (JDK 7), and only since 
starting to use these two, i started having Kernel Failure warnings on 
Fedora 11.
By looking into the detail i found out that it has something to do with 
closing an sctp socket.

I was wondering if others have this too. I haven't posted the failure 
yet with the Linux Kerel group.
I would like some feedback from this mailing list to first find out if i 
am the only one and should look into my system or forward the problem.
I am also not sure if this is lksctp related or SCTP API related. The 
word 'kernel' makes me believe the first one but the cause could be in 
the second one.

Here is the trace :
