Hi Florin, This crash was due to setting hard limit on /dev/shm partition to 100 MB. After increasing that I am able to scale more connections.
For fifo allocation, I see that we can use either shm or memfd. Is there any recommendation/preference on which one to use? Does memfd also internally use /dev/shm for memory allocation?
