error when closing subflows #4

Open FaZoREX opened 7 years ago

FaZoREX commented 7 years ago

hello

in a client-server program I encounter this error on the client side when closing some mptcp subflows and create new ones during data reception from the server:

# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0x00007f79191a7c9f, pid=3322, tid=0x00007f79195ab700

I appreciate any help.

thanks for the reply, basically I open 15 subflows and after that I want to close one of them and open a new one with another port continuously, but the mptcp tuples at some point returns invalid ip addresses. and I think this leads to the segmentation fault after I open and close around 100 subflows. the following is the output of the mptcp tuples:
