Just unload the SCTP module by the folllowing commans

$ [sudo] modprobe -r sctp

Some old Linux distribution doesn't have a module unload routine. You'll need to blacklist the module in modprobe.conf before it ever loads on bootup. Once its loaded it can't be unloaded.

Other options

$ [sudo] rmmod -f sctp 

you need CONFIG_MODULE_FORCE_UNLOAD. Without it rmmod -f doesn't work.

Are the values in /proc/sys/net/sctp/sctp_[rw]mem honored? Or are they overridden by those in /proc/sys/net/core/[rw]mem_*

Furthermore, the kernel documentation states that sctp_wmem has no effect, but makes no such mention for sctp_mem and sctp_rmem.
