## Symptoms

- The following syntax errors appear after running the *cpstart* command:

```

/opt/CPsuite-R77/fw1//scripts/fwaffinity_mq_apply.sh: line 90: let: cpu_id =  % 2: syntax error: operand expected (error token is "% 2") 
/opt/CPsuite-R77/fw1//scripts/fwaffinity_mq_apply.sh: line 30: 1<<: syntax error: operand expected (error token is "<")
```

## Cause

When there are more than one CPU core on the machine, and the Multi-Queue flags are not set (i.e., there are no '*-tx* ' or '*-rx* ' flags in the */proc/interrupts* ; this is the case on X-Series chassis), the *$FWDIR/scripts/fwaffinity_mq_apply.sh* script still tries to parse the results of */proc/interrupt*.
