Colin,
We are using a table which has an FPT file whose normal size is 45mb - every now and then it suddenly expands to over 2GBWhile a ftp can expand very quickly if you're doing replaces against large memo/general fields, VFP can't handle a ftp in excess of 2Gb. So it may well be an OS artifact. What server OS are you using?
You might also consider using SYS(2012) against the table to check its blocksize. The ftp can grow alarmingly depending on the blocksize- e.g. if the blocksize is 32, VFP will allocate 16K per memo even if it only contains "Hello world". Add 100,000 records and your 1Mb of memo field will need a 1.6G ftp.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
