Hi again,

I have upgraded to FB 2.5 and the firebird.log is flooded with:

TYCO-DA15A15021 (Server) Tue May 14 12:05:56 2013
INET/inet_error: read errno = 10054


This error did not occur with FB 1.5 and seems not to be relates to the socket exception in my previous post.

And the Socket Exception is occurring with FB 2.5. It did not help to upgrade the DB engine.
