It sounds like the table where FoxWeb stores its session variables got corrupted. In general, data tables can get damaged when VFP processes crash, or are killed abnormally. There is nothing you can do about this, other than monitor your server with dedicated software or one of the many online server monitoring services.
 
Regarding the size of the table, FoxWeb reuses records associated with expired sessions. This works better than deleting and creating new records, because it negates the need to lock and pack the table, which would be difficult on a busy server. A 2GB session table is certainly strange. How long is your session timeout and how busy is your server? It would be interesting to find out how many sessions were stored in the table and the distribution of the dates stored in the "lasthit" field.
 
I wouldn't necessarily be worried about an oversized session table. VFP can handle extremely large data tables and performance should not be affected.

Hi,
 
Last night, the server do not respond. Foxweb Broken problem.
 
After investigation, this entry was in the FoxWeb Error Log : 
Memo file c:\foxtempfiles\_fwsession.fpt is missing or is invalid.                                   
 
 
Then I located the file " _fwsession.FPT" in the folder.
 
The FPT was more than 2gig so, I deleted the "DBF, CDX and FPT" and the system return instantly to normal.
 
Is there a way to prevent this?
 
Thanks
