Description
rpcd fails when i try to monitor active connections in luci. At the Moment of testing i had around ~5k active connections.
how to reproduce this:
- have ~5000 active connections
- navigate to
<router ip>/cgi-bin/luci/admin/status/realtime/connections - see failure
/usr/lib/lua/luci/dispatcher.lua:431: /etc/config/luci seems to be corrupt, unable to find section 'main'
what fixes luci again:
service rpcd restart

Research direction
Reproduce the failure with about 5,000 active connections by opening the listed LuCI realtime connections URL on the specified OpenWrt setup. Start with /usr/lib/lua/luci/dispatcher.lua:431 and compare the failure before and after service rpcd restart. Done means the connections view no longer produces the reported corrupt-configuration error under that load.
