In a normal c program, I saw that the segmentation fault in 1 loosely
coupled thread doesn't necessarily affect other threads or the main
program. There, I can check all the threads by process ID of it in every
certain period of time and if some unexepected segmentation fault occurs or
got killed I can re run the thread and it works fine. I can later monitor
the logs and inspect the situation.

But I saw that, segmentation fault or other unexpected error in remotely
launched (using DPDK) functions on different core affects the whole dpdk
process and whole dpdk program crashes.. why is that?

Is there any alternative way to handle this scenario ? How can I take
measures for unexpected future error occurance where I should auto rerun
dpdk remote processes in live system?
