## Symptoms

- * Output of "`fw ctl affinity -l`" command show different results when it is executed multiple times simultaneously.

  *Example*:
  1.

     ```
     
     [Expert@HostName:0]# fw ctl affinity -l
     Mgmt: CPU 0
     eth1-03: CPU 0
     eth1-04: CPU 0
     fw_0: CPU 6
     fw_1: CPU 5
     fw_2: CPU 4
     Interface Sync: has multi queue enabled
     Interface eth1-01: has multi queue enabled
     Interface eth1-02: has multi queue enabled
     ```

  2.

     ```
     
     [Expert@HostName:0]# fw ctl affinity -l
     Mgmt: CPU 0
     Sync: CPU 0
     eth1-01: CPU 0
     eth1-03: CPU 0
     eth1-04: CPU 0
     fw_0: CPU 6
     fw_1: CPU 5
     fw_2: CPU 4
     Interface eth1-01: has multi queue enabled
     ```

* Occasionally, "*fw ctl affinity -l -v*" command fails with following error:

  ```
  
  [Expert@HostName:0]# fw ctl affinity -l -v
  fw: Failed to open file /tmp/fwaffinity_cmd_out.tmp: Unknown error 4294967295
  fw: Failed to acquire MQ interfaces
  Mgmt: CPU 0
  eth1-03: CPU 0
  eth1-04: CPU 0
  fw_0: CPU 6
  fw_1: CPU 5
  fw_2: CPU 4
  ```

* Output of "*cpmq get -a*" command shows correct Multi-Queue configuration for all supported network interface cards.

## Cause

"*fw ctl affinity -l* " command uses a temporary file */tmp/fwaffinity_cmd_out.tmp* during its execution.

When running this command multiple times simultaneously, access to the temporary file might fail. As a result, multi-queue interfaces can be shown as non-multi-queue interfaces.
