Hi Chinmaya Aggarwal, I can see the "vec_resize_allocate_memory" api in the above stack and you are telling that after 7k tunnels this issue is seen. I suspect this issue could be due to memory exhaust in the system. Can you please increase heapsize and statseg size in startup.conf file and check

Re: [vpp-dev] VPP crash while create ipip tunnel after a certain limit

To my knowledge there is no such ratio between heapsize and stackseg. based on your application needs you can tune these values. In your case as the number of ipip tunnels are more you may be required to increase stackseg size to accommodate the counters for those tunnel interfaces. Thanks and Re
