NCS max concurrent peripheral connections

[db_lw]

I am trying to build the NCS sample project "peripheral_lbs" with multiple peripheral connections. Therefore I added the CONFIG_BT_MAX_CONN. Up to 20 the build is working fine but if I increase it further the build stops working.

Is it somehow possible to establish more than 20 connections with NCS?

My interpretation of this following quote from a Nordic guide was that the max connections on Zephyr only depend on the amount of memory you can use.

"... and in fact there is no limitation on the maximum number of concurrent connections in Zephyr." (Building a BLE application on NCS - Comparing and contrasting to SoftDevice)

Thanks in advance.
