I'm testing a process for someone which takes days to run on a 466 celeron with 128 ram. Plenty of diskspace, VFP 6.0/Win98. This process at some point in time will error out with a "File is in use" on a SQL-SELECT statement. The error is not consistent in where it occurs. That error msg supposedly indicates that this process is trying to execute a USE, RENAME or DELETE on a file already opened. I guess a SELECT statement issues an implicit USE, but I see NO reason why this error message should come up. Examination in the datasession window show only a few tables/cursors open. If the process is restarted, which can be started with the record that originally caused the error, it goes through the process just fine but of course, everything has been cleared from the crash. This implies that VFP is having some sort of trouble in memory (or elsewhere) in tracking the many, many cursors, tables that are created/opened and then closed. Doing a CLOSE TABLE ALL is out as the process SCANS thru a table and processes each record individually through a vast series of other operations. Any ideas on what is happening here? It seems that VFP has run out of some resource for tracking the opening and closing of cursors/tables and then generating the error at some point.

Thanks,
Steve
