Hello,

first of all I wish to thank you, the developer and supporter of the
firebird database, for the great job you do!
We are using Firebird for more than 4 years in productive systems and
it served us well.

Now we are migrating to Firebird 2.0.1 and use the JayBird 2.1.1 under
Windows 2000 to connect to the firebird database.

Within the Java application we open to connections to the database.
When the second connection is creating using the charset=UTF8 the
message in the post scriptum is received in the java program.

The firebird.log file just contains the message:

Database: unknown, SERVER/process_packet
Invalid clumplet buffer structure: buffer end before end of clumplet
- clumplet too long

The message is generated in the ClumpetReader.cpp.

What does this message indicate and how can the message be avoided?

With kind regards

Andreas

P. S.:

The message that is reported:
