| Technical Level | Advanced |
| Products | Security Gateway |
| Versions | R82.10, R82, R81.20 |

## Symptoms

- * User's FTP Client shows the following error when transfer of file larger than 1GB is interrupted:


  ```
  
  Content inspection module rejected the requested resource
  Transfer was canceled
  ```

* SmartView Tracker log shows:

  ```
  
  Product = Traditional Anti-Virus
  Action = Reject
  File Direction = By IP
  Scan Result = Failure-reject
  Reason = Archive has exceeded the maximum allowed limits
  ```

* Increasing the file size to scan in SmartDashboard does not help (SmartDashboard - go to '`Threat Prevention`' tab - open '`Traditional Anti-Virus`' - open '`Security Gateway`' - click on '`Settings`' - set the value in '`Maximum file size to scan:`' - install policy).

* Debug of FTP Security Server per [sk90423](http://supportcontent.checkpoint.com/solutions?id=sk90423) shows in *$FWDIR/log/aftpd.elg*:

  ```
  
  kav_clbk_fn: Maximum unpacked size reached, canceling scan... 
  [aftpd  ...]@HostName[Date Time] kav_clbk_fn: got event XXX. kav_init_called=1 
  [aftpd  ...]@HostName[Date Time] '/opt/CPsuite-R77/fw1/tmp/file...': EVENT_RESULT - 
  [aftpd  ...]@HostName[Date Time] CLEAN 
  [aftpd  ...]@HostName[Date Time] kav_handle_result: result = KAV_S_R_CLEAN 
  [aftpd  ...]@HostName[Date Time] kav_handle_result: the archive max nesting level exceeded 
  [aftpd  ...]@HostName[Date Time] AVIMServant::task_handler: Scan failed or virus found for file 161728760. failure type=Async failure(avimh=0x..., cpkioh=0x...)
  ```

* Setting large value for the parameter "*max_archive_scanned_object_size* " in the *$FWDIR/conf/malware_config* file per [sk102974](http://supportcontent.checkpoint.com/solutions?id=sk102974) changes the symptoms - the file transfer is not blocked, but simply times out.

## Cause

Traditional Anti-Virus incorrectly ignores the file size to scan configured in SmartDashboard.
