I had a similar experience just today: in my case the error
was 335544726 (error reading from the connection).

It happened in an application which also uses D6 Indy-Internet
components, and it turned out that trying to send an UDP packet
to an invalid address (0.0.0.0) using Indy caused this error
in subsequent DB operations!!

I can only guess, but it seems that strange things can and do happen
deep inside WinSock... :-(
Eventually, this bad send attempt only causes other TCP/IP operations
to delay too much, and probably interbase uses a (too?) short timeout.

I fixed my problem by avoiding the bad UDP send - and just thought this
is a interdependency of such obscure nature that others might be
interested in hearing about...
