TDiskDB: Insertion failed because database is full: database or disk is full

I have a persistent notification that I don't know how to fix.

Unexpected exception occurred
TDiskDB: Insertion failed because database is full: database or disk is full

It clears itself [thankfully] but pops back up again immediately. I don't know where the database files are located, but none of the disks are full. Is there a method to make the database bigger, or configure less logging, or both?

Networx 5.3.0 64-bit

Normally this error doesn't pop up unless the disk is really full or something nasty happened. Check either of these locations

c:\Documents and Settings\All Users\Application Data\SoftPerfect\NetWorx

or

C:\ProgramData\SoftPerfect\NetWorx.

I'm running Windows Server 2008 R2 on my desktop, so that first folder isn't found.

I did find C:\ProgramData\SoftPerfect\NetWorx though, and there are three files in it including NetWorx.db. It's only 750KB, and the disk has ~5GB free.

I turned off the notifications [until I found a cause] but now that I've turned them back on they are not appearing. It seems to have solved itself.

Thanks anyway

Running on WinXP SP1 x64 and Networx 5.3.0.
In C:\Documents and Settings\All Users\Application Data\SoftPerfect\NetWorx there are 3 files:
21.05.2014 21:24 5388288 bytes NetWorx.db
25.04.2014 06:21 32768 bytes NetWorx.db-shm
21.05.2014 21:25 1065848 bytes NetWorx.db-wal
I had a little bit less than 1GB free, then I make the free space 2-3GB and the message continues to appear. It appears for some seconds, disappears and the story begins again. This situation continues more than a day.

It might also be a database corruption issue.

Download SQLiteSpy tool and execute the following query (select Execute - Execute SQL in the main menu):

pragma integrity_check;

If the result is anything other than OK then the database is likely to be corrupted.

I have run the integrity check, while the program was running and it gives "ok". But the message continues to appear.
Finally I have stopped the software, installed the last version 5.3.1 and when I start the software the message did not appear.
The only thing that I have noticed is, when I try to export or backup, the program pushes one of the CPU cores to 100% for 5 minutes or more, and after that the dialog box with the "save as" appears. The data is for some years and the NetWorx.db is nearly 5-6MB. Can this cause some problems? Should I do something, like reset or something else (maybe export the databse, reset the counters and then reimport the database, so that some errors are removed)?

It's clearly not because of the database size, I am not sure what it might be though.

Try to VACUUM the database using the same SQLiteSpy tool (Execute - Vacuum database).
