Hi,

Network extension crashes when we set network settings with 2048 IPv6 routes. We have been using 1024 IPv4 and IPv6 routes without any problem however when we try to increase the size to 2048 routes, Network extension crashes saying "memory limit exceeded".

Is it not possible to configure 2048 routes on iOS? Is there any workaround?

Thanks in advance. Meera Mohideen

Why do you need to create that many routes in the routing table? Are you able to get away with create wildcard routes for some of these?
