If very many transactions are processed when editing on a PGDB (MDB), the following error message may occur.
File sharing lock count exceeded. (Error 3052)
This problem often occurs, for example, when using the UT NCS Export (utncsexport.exe).
The error occurs if the number of locks required to perform a transaction exceeds the maximum number of locks per file.
The maximum number of locks per file can be increased by a parameter in the registry to avoid the error message.
The parameter in the registry can also be set by the AdvancedArcMapSettings.exe tool from Esri.
Administrative authorization is required.
