It probably won't mean anything to you, even if you got a more detailed
explanation. AFAIK, 'Bad file number' means that the software (Firebird)
has opened a file (i.e. a network socket) and got a 'file number' (i.e.
a descriptor) with some number (for example: 5). After some time,
Firebird tries to read/write to that socket and uses it's file number (5
in our example) to access it. However, from some reason (network failure
or something) the operating system has closed that file, or made it
invalid, or whatever - which caused the file number not to be present
anymore (i.e. number 5 is not found in /proc/self/fd). At time point the
OS refuses any operation on the file/socket.

In short: it means that there is some kind of network failure reported
by the operating system, and there is no way Firebird could know more
about it.
