> When I run the command *mesos ps --master=$MESOS-MASTER:5050*, the following exception raised:
> {code: title=exception.sh}
> File "/usr/bin/mesos-ps", line 232, in <module>
>     main()
>   File "/usr/bin/mesos-ps", line 217, in main
>     sys.stdout.write(columns[4].truncate(mem(task, statistics)))
>   File "/usr/bin/mesos-ps", line 93, in mem
>     mem_rss_bytes = entry['statistics']['mem_rss_bytes']
> KeyError: 'mem_rss_bytes'
> {code}
> I tracked it and found that some mesos slave nodes can't return the statistics yet now. In my special case, the disk volumn of some my mesos slaves is 100% full.
