I am using lksctp-tools-1.0.6-3.el5 (Red Hat Enterprise Linux Server release 5.8 (Tikanga)) on one machine and lksctp-tools-1.0.10-7.el6.x86_64 (Red Hat Enterprise Linux Server release 6.5 (Santiago)) in another machine. I am trying to establish a SCTP association via JAVA application. SCTP server(172.16.150.14) was running on the machine (lksctp-tools-1.0.6-3.el5) and my JAVA SCTP client(172.16.150.69) was creating association through machine (lksctp-tools-1.0.10-7.el6.x86_64). We are getting multiple ABORT while establishment phase itself. I am providing the pcap details for reference.

Kindly help me.
I have tried with same version of lk-sctp : lksctp-tools-1.0.10-7.el6.x86_64 on both my machines. It is working fine for now.
Tested with sctp_test commands:
Please find pcap file for above command as attachment.
