Hi

when doing the actions below I get a panic.

- echo 1 > /proc/sys/net/sctp/addip_enable
- In a C-Programm
   - socket(AF_INET,SOCK_STREAM,IPPROTO_SCTP);
   - connect(....)     (with correct filled parameters)

Its no process (waiting in accept) neccessary

Can you show us the panic message and your C prorgam?
This would help reproducing the panic...
