Storm kill fails with exit code 143

[Mitchell Rathbun (BLOOMBERG/ 731 LEX)]

Recently our shutdown script failed when calling storm kill with a return code 
of 143. Typically this means that SIGTERM was received and the process was 
terminated. I see in https://issues.apache.org/jira/browse/STORM-2176 that it 
is possible to get this exit code if a topology takes too long to come down. 
However, we are running version 1.2.1 of Storm, which should have the fix 
mentioned in the issue. Is it possible that we have the same cause for our 
error? When this occurred, many topologies were brought down at once, but only 
this one topology seemed to have an issue.
