Bug Blocker Resolved Fixed Michael MacDonald Maloo HSM Thu, 6 Mar 2014 20:53:00 +0000 Fri, 2 Aug 2019 19:11:48 +0000 Tue, 11 Mar 2014 13:47:11 +0000 Lustre 2.6.0 Lustre 2.5.1 Lustre 2.12.3 Lustre 2.6.0 Lustre 2.5.1 0 7 <p>Writing to the event FIFO uses fprintf() with an unbuffered stream and there is no synchronization around calls to llapi_hsm_write_json_event() that I can see. So since the CT is multithreaded expect more such malformed events.</p> <p>Looking into this.</p> <p>I've been able to reproduce this locally by running test_71 in a loop. Will implement a fix and soak it for a while this morning before pushing for review.</p> <p>Pushed <a href="http://review.whamcloud.com/9553" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/9553</a> for review. Soaked this locally for 64 runs, zero failures. Without it, was getting failures about 33% of the time. Lesson learned.</p> <p><a href="https://jira.whamcloud.com/secure/ViewProfile.jspa?name=jhammond" class="user-hover" rel="jhammond">jhammond</a>: I've added you as a reviewer.
