subflow closing error

[FaZoREX]

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.
