Subject: Fix third start fails
X-Git-Tag: accepted/tizen/unified/20180718.071534~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=17670ed35cb31fe42eda81766a4f7b8903296500;p=platform%2Fcore%2Fsystem%2Fswap-manager.git

Fix third start fails

Problem:
  - RequestQueue::do_all() can not processed all requests
    because Request::execute() can throw exception.

Solution:
  - Encapsulate catching exceptions to Request::execute().
