Hi John,
your observation is absolut right. If you drop a table
this will be done asynchronous by a server task. First
the file directory of the correspondig file will be
removed and then the b*tree is released. If you shutdown
the dabase before this operation is finished you have
unreferenced pages in your data area. The only way to 
remove them is:

bring the database in state cold resp. admin and execute
one of the following commands:

in 7.3: dbmcli -d .. -u .. util_execute verify 
in 7.4: dbmcli -d .. -u .. util_execute check data with update

Regards,

Subject: The number of data pages is increasing extraordinarily 


Hello,
some days ago i posted a mail, because my number of pages are increasing.
Now i can reproduce the problem.

1. starting database
2. drop table
3. create table
4. dataload ( 270.000 items )

during this process i watch the statistic in dbmgui. The pages after the
drop table don't become free. After the dataload is finished the database
works a lot and sets the pages step by step free. When i shutdown the
computer before this process has stopped these old-pages becomes permanent
data. So my database grows.

                        number of pages
start                   13723
drop table              13723
dataload start          increases
dataload stop           17500
the database works      13723

Any Ideas what to do ?
- I'd like to know, how to stop this situation 
- Is it possible to free the pages . I looked for a way to reorg the
database. I think the pages a marked as old. How can i identify them

John
