Bug Major Closed Won't Fix Public Steve Yen Thuan Nguyen 1.7.0-release-notes 1.7.1-release-notes Fri, 15 Apr 2011 18:38:47 -0500 Thu, 10 Jan 2013 01:21:37 -0600 Mon, 16 May 2011 20:24:43 -0500 1.7 alpha 1 bucket-engine 0 0 Test on build 177. I don&#39;t see memcached process after uninstall membase server I still see membase serice after uninstall membase server version basestar-182 in ubuntu 1004 32bit<br/> <a href="http://screencast.com/t/qeOuiivIQ">http://screencast.com/t/qeOuiivIQ</a> The remaining process is an epmd process, which is not the memcached process, but is instead the erlang port mapper daemon (epmd).<br/> <br/> There&#39;s already some older bug which covers the issue that epmd is still running after an uninstall on linux, so marking this one as a duplicate. Hearing more instances of this still since yesterday.<br/> <br/> Farshid is adding &#39;ps&#39; output to the test suite so we can get more proof.<br/> this behavior is expected so that we dont lose any data during uninstallation. <br/> the workaround is that the user <br/> 1- do not uninstall membase if its still processing data in the persisten queue <br/> 2- run killall -9 memcached after uninstall but before reinstallation Killing memcached harshly would lose customer data (items in the persistence queue that are still waiting to drain to disk).<br/> <br/> Although an uninstall is a strong user command, the &quot;do no harm (do no data loss)&quot; philosophy seems to be the safe choice.
