The beacon-period gate in online_notify already rejected a parse failure and a non-positive value, but epicsScanDouble parses "nan" and "inf", and maxPeriod<=0.0 is false for both, so a non-finite period reached the beacon delay loop. A NaN maxdelay makes delay<maxdelay false forever, pinning the beacon interval at the 0.02 s startup value - a ~50 Hz beacon flood on every configured interface; an infinite maxdelay lets the doubling delay grow without bound, silencing beacons entirely. Gate on finite() (from epicsMath.h), matching the client-side EPICS_CA_MAX_SEARCH_PERIOD handling in udpiiu.cpp, and name the actual problem in the diagnostic instead of "float fetch failed" (the message already covered the non-positive case, which is not a fetch failure).

make
For more information on how to install on your system see the Installation page of the documentation.
Quick run a softIOC
After building, you can run an example soft-IOC (Input/Output Controller) which runs a Channel Access server.
./bin/*/softIoc -x first
Run the dbl command to list the records it provides:
