hello, i have a big problem and no idea, where it comes:

..............................
Windows 2003 Server SP1,
Firebird 1.5.4 Superserver
(standard config)
IBO 4.7.16
database is on local server
hardware:
Xeon cpu 3.60 GHz, 6 giga RAM
..............................

from time to time i get:

2007-08-19 14:37:47; ERROR: ISC ERROR CODE:335544726

ISC ERROR MESSAGE:
Error reading data from the connection.

STATEMENT:
TIBOInternalDataset: "<TIBOQuery>.<TIBOInternalDataset>."

5-10 times the day, but no entry in the firebird.log that
there was an connect error or anything.
I checked all selects and so on, found no error.

regards
gerhard
