I have had 3 times now database corruption of an FB1.5 database
after these happenings:

1. The disk containing the DB is running low on free space.
2. It seems to me, that as a result of this, the machine runs out of
RAM. Note however, that the swap file is on a different disk.
3. After a normal shutdown of the machine, the database file is
corrupt having page pointers pointing behind the EOF.

Is such corruption known problem?

Here is an excerpt of the firebird log. There are no write errors
for the db file.
