Description

I was creating a test database on an external USB drive formatted as FAT32- it contains some tables that have quite large binary objects in: This was in conjunction with Hibernate. I got this rather cryptic error message.

Looks rather scary:

18:02:37,550 WARN JDBCExceptionReporter:77 - SQL Error: 40000, SQLState: 08006
18:02:37,550 ERROR JDBCExceptionReporter:78 - A network protocol error was encountered and the connection has been terminated: the requested command encountered an unarchitected and implementation-specific condition for which there was no architected message

Initially it didnt even occur to me that this may be due to me using a FAT32 drive, but eventually I figured out that the table's file had got to the operating FAT32 limit: I had a file of 4,194,272 KB.

In the derby log, there's a more revealing, but still incorrect, error message:

The error is still strictly speaking incorrect - my disk is far from full, but I have created a file too big for the disk type - but the error is at least closer to the truth and this would be useful information for the derby client to display rather than the rather scary looking message I was getting.
