Dear Deepa Sudarshan,

if OOTB ABORT handling is turned on (default for sctplib), more than one
instance cannot run on the same host. You will see ABORTs in a Wireshark
trace.

To run multiple sctplib instances on the same host, turn OOTB ABORT handling
off. test_tool has no option for this yet. Adding
SCTP_getLibraryParameters(&params);
params.sendOotbAborts = 0;
SCTP_setLibraryParameters(&params);
directly after sctp_initLibrary() should solve your problem. ("param" is of
type SCTP_LibraryParameters. Also add declaration "SCTP_LibraryParameters
params;" in main()). Also see the other sources.
