So, which is correct? It always fails, or it sometimes works? If it
sometimes works and sometimes fails, where do the failures occur? at
login? when running a query? something else?

If something crashes the server, then client programs will lose the
connection! Are you saying that other programs also crash the server?

What connection path string(s) do you use in the applications? I mean
*exactly* what connection path strings...

Do you use database aliases?

No, but it can CRASH the server, as it is obviously doing. You eliminate a
bad UDF as the cause. Are you using an international character set? If
so, which one?

True. But on Windows anything is vulnerable to wrong configuration and bad
access paths.

Have you eliminated the possibility that some or all of your clients are
using the wrong client library? Did you read the v.107 release notes
(available from www.ibphoenix.com)? There are some highly important issues
documented there about client installation on the RC8 for Win32.
