Steps to reproduce:

1. Have ~5k active connections
2. go to: Status → Realtime Graphs → Connections
3. wait a few seconds
4. reload page because it will not respond anymore
5. see error message /usr/lib/lua/luci/dispatcher.lua:431: /etc/config/luci seems to be corrupt, unable to find section 'main'

Actual behavior:

• Error message /usr/lib/lua/luci/dispatcher.lua:431: /etc/config/luci seems to be corrupt, unable to find section 'main'

Expected behavior:

Additional Information:

At least 22.03.[0,1,2,3] is also effected, 21.03 probably too. See #4758 for reference.
