Could we catch the explicit exception?
Also, I think we could this like:
```python
cmd = "%s -P |grep %s | grep LISTEN | awk '{ print $2; }' | xargs kill"
...
lsof = "lsof"
subprocess.check_call(cmd % (lsof zinc_port), shell=True)
...
lsof = "/usr/sbin/lsof"
subprocess.check_call(cmd % (lsof zinc_port), shell=True)
```
