Problems of connection with firebird beta 2.1

I need a solution to this problem that has been bringing to me of head for a long time:

In a local servant I have developed in asp.net an application Web whose data base is administered by firebird. Until recently the version that used he was firebird 2.0 and, although there were no problems at the time of executing the application, every certain time -they could be two days- to I add it became disconnected of the local servant by some intrinsic problem of the BD administrator, being this one assets.

This problem, apparently, is solved in the new beta version of firebird, firebird 2.1. Nevertheless, far from being a solution, one has become a new puzzle that no matter how hard treatment to solve, there is no way. After making the installation of the new version, when executing the application in localhost gives the following error me of connection:

“The displacement and the length are outside the limits for this matrix or the count is superior to the number of elements from the index at the end of the origin collection.”

Request that if somebody has had east problem or knows how to solve it, me of an answer because no longer I know what to prove more.
Thank you very much, beforehand.

You should describe your problem more clearly and/or in more detail, and I think the error message you mention didn't came from Firebird but from the application, where you should check what triggered it.
Note that Firebird 2.1 is alpha/beta quality so you might want to check the project bug tracker

hmm it seems like a port error is the 3050 open?is there any firewall whats error code?what you use for connect?etc
