Dear Jose,

we are using the sctplib in a multithreaded way in the
socketapi library. We do not support multithreading
in general in the sctplib, but you could have a look
in the implementation of the socketapi lib.

So I would suggest
1. Upgrade to the pre18 version. We fixed a lot of bug since
pre16.
2. Use the socketapi lib which supports multithreading.

Best regards
Michael
