gstrtspconnection.c assersion occurred

[Sooeun Jang]

hi,
i'm just beginner of gstreamer and I thank all gstreamer maintainers.

now I'm developing rtsp streaming server using gstreamer and
gst-rtsp-server.

my pipeline is seperated with shm, cause it should run record pipeline
parrallel to live stream. 

"rtspsrc location=%s protocols=tcp latency=%d is-live=true"
" ! rtph264depay"
" ! video/x-h264, stream-format=(string)byte-stream, alignment=(string)nal"
" ! shmsink socket-path=%s shm-size=10000000 wait-for-connection=false"

"shmsrc socket-path=%s do-timestamp=true is-live=true"
" ! video/x-h264, width=(int)1, height=(int)1, framerate=(fraction)0/1,
stream-format=(string)byte-stream, alignment=(string)nal"
" ! rtph264pay name=pay0 pt=97

The proplem is application aborted by raising gstrtspconnection assersion.
When I run my application and some hours or later going on, 
It suddenly terminated with signal 11, segmentation fault.

These are gdb tracking messages.

and these are pointed source codes in gstrtspconnection.c

      while (drop_messages > 0) {
        msg = gst_queue_array_pop_head_struct (watch->messages);
        g_assert (msg);
        drop_messages--;
      }

      *g_assert (watch->messages_bytes >= bytes_written);*
      watch->messages_bytes -= bytes_written;
    }

I'm using all 1.15.2 version of gstreamer and plugins.

Is there anybody have advices for checking this error? 

thanks & regards
