There is only one UDF .so file per application category per database per node.
| Application Category | .so File Format |
|---|---|
| > 0 | libudf_dbid_librevno_AppCat.so |
| = 0 | libudf_dbid_librevno.so |
When you create, replace, or drop a UDF, the UDF .so file for that database must be relinked with all the other UDF object files and then redistributed to all the nodes. The 5607 Warning message is normal.
