I'm having an issue merging records from eight existing geodatabases into a single geodatabase. When I merge the records, not all of the records make it into the target file geodatabase. I have found that I'm missing approximately 3000 records (~46,000 out of 49,000 records). The strange thing is, if I create a new record in the target file geodatabase (whether by create feature or by copying feature), it seems another record goes away. It's like I'm hitting a record limitation for the target file geodatabase, but this seems weird.
Any suggestions on settings to check or things to keep an eye out for? I have attempted this multiple times with the same result. Thanks in advance.
