    Threads are getting stuck after smartclient upgrade

    Wondering if this could be smatclient jar files issue, we are using weblogic 10.3.3.1 and Smarclient v9.0p_2013-08-16/Enterprise Development Only (built 2013-08-16).

    We have no similar reports. We definitely would suggest checking for duplicate .jars in your installation.

    What exact version did you upgrade from?

      I have verified that we don't have duplicate jar files, I don't remember the specific version but it was Smartclient 7.

        OK, we'll need some way to replicate this behavior in order to figure out if it's a bug, or how your usage needs to be corrected.

        As a starting point for narrowing down the issue, you should look into whether it's something that happens every time you load a particular DataSource vs whether it's an intermittent behavior.

        Also, the stack trace does tell us this is somehow related to DataSource pooling - please review this background information on DataSources and threading, and be sure your settings match the recommended ones.
