This happens once in a while in production. It is not reproducing in dev setup. We are using dotconnect for Oracle 8.3.161.6. Any thoughts?

It's necessary to localize the issue and find out what steps to perform in order to reproduce it.

Please also tell us which operating system is used on the user computer and which Oracle version is used.

If possible, try using the latest version of dotConnect for Oracle.
It can be downloaded at http://www.devart.com/dotconnect/oracle/download.html (trial version) or from Registered Users' Area (for users with valid subscription only).

Is the issue reproduced with the latest version?

we are testing our application with 8.4.333 currently. It fixes a multithreaded connection pool issue mentioned below as per your rev. history. This System.IndexOutOfRangeException problem seems to be related. do you think moving to 8.4.333 will help?

8.4.333 15-Jan-15

•The bug with throwing System.InvalidOperationException by Devart connection pooling in multithreaded applications under high loads is fixed

We are not sure if 8.4.333 fixes the System.IndexOutOfRangeException issue because we are unable to reproduce it and find out the reason of the issue.

Since you already test the 8.4.333 version, please try using your application with this version for some time and check whether the issue is fixed. Please tell us about the results.
