## Known Problems

The following section describes problems that were found in WebLogic RFID Edge Server 2.0 Service Pack 1. Entries include a description of the problem, and a workaround or solution where appropriate.

Tracking Number | Description and Workaround
--- | ---
[vendor issue] | The tag programming feature (including tag locking and killing tags) in Symbol readers (XR400 v2.0.18 and AR400 v5.0.4) might not work due to reader firmware issues. Workaround or Solution: Restart the reader (power off and on).
[vendor issue] | When using the Printronix Device Management Language (PXML), if the Ethernet cable connection is lost, the Edge Server has difficulty reconnecting to the printer due to a PXML API issue. Workaround or Solution: Restart the Edge Server.
| When using the Printronix Device Management Language (PXML), the Edge Server attempts only two RFID tag programming retries before declaring a failure.
TT4335 | If you configured the CAEN Technologies A928 RFID reader in Edge Server 2.0 and upgrade to Edge Server Service Pack 1, the Edge Server will not start unless you have installed the 2.2 version of the CAEN Java library. Solution: Copy the `CAENRFIDLibrary.jar` version 2.2 file to the `lib` subdirectory of your WebLogic RFID Edge Server Service Pack 1 installation before starting the software. Workaround: Edit the following parameter in the `edge.props` file: `com.connecterra.ale.persistence.allowBadData = true` The Edge Server starts (it ignores the configuration errors from the state persistence data), however, the CAEN reader driver remains unavailable without the 2.2 version of the library.
