Hello all,

Can't seem to find anyone else seeing this. Hence this request for help

Environment:
server: ubuntu running fb 1.5.3
devel client: running winxp with fb 2.0 rc3 and IBExpert

In ibexpert I have the connection to the 1.5.3 server using the
fbclient.dll ver 2. The local connection on server 2.0 is also using
the fbclient.dll ver 2.

I have been making revisions both to the content and structure of the
database from the server by backing it up, and restoring onto the ver
2.0 client. When i am satisfied with the changes made, I run a
database compare from IBExpert which prepares a DDL script to
impliment the changes. I then pick through the statements one at a
time onto the live fb 1.5.3 server. Any content changes I hand do. I
am not using any of the features unique to ver 2. It was actually a
mistake that 2.0 was on the devel client as I had though the live copy
was running ver 2 originally.

This error started appearing the last time I attempted to do my
regular backups. It is appearing on both the server and client copies.

Error: "Firebird error. arithmetic exception, numeric overflow, or
string trunication. unknown ISC error 0."

This error stops the backup from completing. It seems to die near the
end when it is working through the Generators.

I do use a few calculated fields, though deleting those did not fix
the error. I have not dropped the tables that I imported just before
I started seeing the error, as they have numerous keys and constraints
and hence a pain to drop or delete all.

Since the error is pretty ambiguous, I thought I should not try to
hack through a fix and make things worse since I am unable to backup
successfully. I did try to validate the database but a similar error
prevented validation. Error: "Connection error.
bad parameters on attach or create database.
secondary server attachments cannot validate databases."

I did try deleting the generator that the backup log failed at. when
i did that I got a new error:
"Arithmetic overflow or division by zero has occurred. arithmetic
exception, numeric overflow, or string trunication. gds_$receive failed."

Any help would be appreciated.
