I have a crystal report which accesses two databases with a sub-report. The main report has a start date time and an end date time as its parameters. This main program queries one databases and finds all of the entries which correspond to occurring within this date time range. For ach entry it generates a character key from various fields of data within this database. It uses this key that was generated as a parameter to the sub-report.
The subroutine only looks at the second database. Using the passed key, it generates a few counts based on existence of records containing this key which are displayed along with the key.
The main report only accesses one database and the sub-report only accesses the other database.
The report can successfully run about three or four times before the error message is displayed. I can run the same report with the same parameters and it will succeed for a few times and then fail. It is not always three or four times but that is most often the count. This failure dos not occur at the same place within the report. When is fails, the error may occur on the first pages, in the middle pages, or towards the last pages.
When it fails, it locks me out and I have to stop Crystal Reports ad start again before I can continue.
I am running Crystal Reports 2013 Support Pack1
Version 14.1.1.1036

The two databases are both SQL Server but cannot be combined.
