Struct IocAlreadyInitialized 

pub struct IocAlreadyInitialized;

PvDatabase::begin_load was called on a database whose iocInit has already run — C’s getIocState() != iocVoid (R19-63).

The Display text is C’s errSymMsg(S_dbLib_postInitRecRegister) verbatim (dbStaticLib.h:269), which is what dbCreateRecord prints:

epics> dbCreateRecord(pdbbase,"ai","NEWREC")
ERROR: 33554463 IOC already initialized - No new records can be added
