Hi!

I am testing an association between two IP addresses. I am using two
machines (hosts) to perform that test.

I am getting strange behavior in the shutdown process.

In some instant I call sctp_shutdown() and wait for a ShutdownComplete
indication. But in some cases that indication never arrives. The
ShutdownComplete indication never arrives in another host to. I cannot
specify when it occurs exactly. I simply send some messages and try shut
down, but in some cases the ShutdownComplete indication never arrives.

Is that behavior reported by anybody else?
I do not know about a problem in that area...

PS: I am executing sctp_eventLoop() in another thread. I am using
mutexes to avoid race conditions.
I guess this might be the problem. You might want to look at the
socketapilib to see how the sctplib can be used in a multithreaded
environment.
