Canvas text is wider than the maxcol specified

[VictorCano]

Hi!

I was just using crate-top while stress testing a cluster, and it exited a few times with the following error:

File "/Users/victorcano/Desktop/playground/crate-top/eggs/urwid-1.3.1-py3.5-macosx-10.11-x86_64.egg/urwid/canvas.py", line 356, in init
raise CanvasError("Canvas text is wider than the maxcol specified \n%r\n%r\n%r"%(maxcol,widths,text))
urwid.canvas.CanvasError: Canvas text is wider than the maxcol specified
89

I believe it's because of the readings giving more than 100% of CPU at the time.

Thanks!

hi @VictorCano
thanks for reporting. the CPU usage shouldn't actually exceed 100%
need to investigate how/when this can happen.

[VictorCano]

Don't know why but it keeps happening, it only happens when a node is under heavy usage.
To be able to fix it I forced values on progressbar > 100% to 100%.

Tested for over an hour connected to the cluster and it didn't occur again, will reference the change here.

Having this problem as well, just about as soon as I hit "1" or "2" I get the maxcol error, even if I make my terminal size very large.

BTW, here's a sample of the output of /_cat/nodes

Every 2.0s: curl -sS http://172.25.29.98:4200/_cat/nodes?v|awk 'NR<2{print;next}{print|"sort"}'
