hi, i use system to make a service to bringup my robots launch files;

mostly time it can work. but when this sysytem run for a long time , i find some topic cannot be processed by runing node, almost most node doesnot receive topics from others , but i can also echo the published topiic data.

i try to use rqt_graph to find somthing ,but it looks like everything is ok. the solution for me is to restart this service.

what could i do to diagnose this problem
