Process is a bit of a misnomer, “cooperative multitasking thread” would be more accurate. Src/vlib/main.c makes no effort to interrupt process nodes. If a process runs forever vpp will have a bad day.
Recitations: which version of vpp is involved? Please send “show run” output for the process node in question. The process might be waiting on an event which never happens, or for the clock to reach a time so far in the future it won’t happen in one’s lifetime. Worse luck might involve memory corruption or an issue with the timer wheel code. HTH...

Sometimes we observe that this process node is suspended indefinitely. I know that if any process node is taking Unreasonably long time such nodes will not be scheduled further. But not able to figure out in code where this is done. Can anyone point me to the code where we are tracking time taken by each process node and suspend indefinitely if it is consuming more time.
