Throw an **assert failed: block_next tlsf_block_functions.h:94 (!block_is_last(block))** after so many sctp sendv error 11: No more processes

[qingwa2009]

If not use usrsctp, after serveral minutes normal work, the data channel is still open, the browser can send msg back to esp32 normally,
and the esp32 is still sending the msg , i check with wireshark, the computer can recv the msg, but the browser can not trigger the recv event!!!

When i enable the usrsctp, sometimes it works normally about several hours, sometimes several minutes, but finally it would assert failed!

Do you have the same problem?
