Description

After browsing other issues, it seems the error nospc.U should not be thrown whenever there is still space in the disk.

The issue is that I have a table with about 80k rows and 3 rows for some reason became corrupted, The rows where inserted about the same time. The rest of the table and the DB is working ok for weeks until I noticed the problem with those 3.

The error is triggered when I try to set a value update in the timestamp column in any of those 3 rows. If I set that column to null it allows me to update other columns.

I'm not sure if it is related but I have added 3 other columns to that table after it was created but not the timestamp one that is failing.

The way I worked around this problem was dropping and recreating the timestamp column.

Following the derby log, the problem is in the column named "last_update":
