## Symptoms

- * After installing R81.20 Jumbo Hotfix Take 90 or 92, the **Logs \& Monitor** tab in SmartConsole does not display logs, and the page remains blank. The following message appears:

  `The session has expired. Please try to refresh the view.`

  **Additional Observations**:
  * The *fw.log* file is growing, indicating that logs are being recorded.
  * The Log Indexer is indexing the logs. The *log_indexer.elg* file shows `Sent Current: ###`
* The */opt/CPrt-R81.20/log/RFL.log* file contains these lines:

  `
  ERROR [pool-1-thread-3]`  
  ` com.checkpoint.rfl.exceptions.DefaultUncaughtExceptionHandler.uncaughtException:3 - uncaught`  
  ` exception from thread id: [68], name: [pool-1-thread-3]`  
  ` 
  java.lang.NoSuchFieldError: org/apache/cxf/message/Message.CONTENT_TRANSFER_ENCODING`  
  ` 
  `

## Cause

A deprecated *.ja*r file causes a code dependency issue.

## Solution

This problem was fixed. The fix is included in:

* [Jumbo Hotfix Accumulator for R81.20](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.20/Default.htm) starting from Take 99
