[tipc-discussion] TIPC socket alive even when the process is killed ( using SIGKILL)

[prakash b. <ps1...@gm...>]

Hi  John/Xin,Tung,



We are facing an issue while closing the TIPC server socket. We are running
multiple applications which are in turn creating TIPC sockets.

As part of the shutdown, we are terminating all the processes using
SIGKILL. We are expecting the tipc sockets to be closed automatically by
the kernel after some time.

But sometimes ‘tipc socket list’ is still showing a few sockets as alive.

Now when we restart the application, the system has two sockets with the
same tipc address.


Isn't the tipc sockets should have been closed automatically by the kernel
once the application is killed ?


Kernel version : 4.19.81

Socket type :      SOCK_SEQPACKET



Would appreciate any help.


Thanks,

Prakash
