In the BugParade, bug #4113225 (at
http://developer.java.sun.com/developer/bugParade/bugs/4113225.html) details
what I believe to be your problem - concurrent access of ODBC crashes the
server. There is even sample code to reproduce the problem. Sun's
evaluation - Not supported, not to be fixed, use commercial.
Also, while JDK 1.1.6 does run on 2000, Sun only recommends using
the JDK 1.1.8 on Windows 2000 (and only JDK 1.1.8_007 on Pentium IV), if you
are going to use JDK 1.1.x. (I couldn't find any specific warnings but did
find a few bugs in the Bug Parade).
So, I would suggest change your database drivers. I believe that
there is a free software effort at freetds.org and I would like to plug the
drivers we use from inetsoftware.de (we use it without any problems). I
would also suggest upgrading your JDK to 1.1.8. I would not use MySQL in
place of SQL Server. If you must leave SQL Server, try PostgreSQL. (MySQL
doesn't pass the ACID test, which causes all sorts of problems for people
worried about data consistency and integrity)
