# 2065 ODBC Driver Not Handing Multi-Threading Properly

---

I thought I’d first update you with where we are at concerning the ACCESS VIOLATION that we were receiving with Sun’s JDBC-ODBC bridge.

We have narrowed down all access to 1 single process in our server.

All calls to the database that create a connection and execute a query have been synchronized in java so that multiple threads can not access or create a new connection in the database at the same time.

The calls from this single process themselves are happen sequentially.

We can reproduce the ACCESS VIOLATION using another third party jdbc-odbc driver. (OpenLink)

This continues to bring down the JVM. This crashes our server obviously. The violation happens randomly, but fairly quickly on an SQL statement that may have run successfully 5-1000 times in previous calls.
