|Subject||Re: [firebird-support] firebird service terminated unexpectedly|
May be upgrading will solve the problem but, for what you say, it is not sure that 2.1.7 will be the solution.
Anyway, it is strange that the same version in many other similar networks has no problem. Even in the same network it was working without problems many years till 05/2015. And it is still working in many others with the same version of Windows.
It would be interesting to know the reason of the problem. I searched in Google and found that this may be related with some hardware, a switch or something like this. It´s a possibility...
Does anyone know something about which may be the reason of this problem?

At minimum, upgrade to 2.1.7 as it there have been several crashes fixed
since 2.1.4. However I have seen a similar problem with 2.1.7 as well. You
might have no choice but to upgrade to 2.5.4 (or 2.5.5 that will be
released in the near future).
The log seems to indicate that something or someone is sending malformed
packets to the Firebird server, but given the time between its occurrence
and the actual crash, I am not sure if that is the reason. Similar problems
were the reason for releasing 2.5.3 Security Update. As far as I know this
fix ended up in Firebird 2.1.7 as well, but I am not sure if this is
actually the same problem.
