I think my derby database keeps on getting corrupted

[Enter The]

Hi,

Every now and then my derby database gets to a stage where I'll get a
disk full message when I try to insert rows.

The database will only be around 2megs in size, and I have 50 Gigs
left on my disk. If I delete my database folder I can recreate
everything OK, though that means that I lose the data that's already
there.

Has anyone else experienced this problem? I have a feeling it might
be due to corrupted tables. However, I can't find a repair function
for derby.

Thanks,

Enter.
