Hi, Hope this could help, I've encountered this issue myself not to long ago on Ubuntu 12.04 host, it didn't happen again after messing with the Kernel Semaphore Limits parameters [1]: Adding this [2] line to `/etc/sysctl.conf` seems to do the trick. - Roey [1] http://paste.openstack.org/show/73086/ [2] http://paste.openstack.org/show/73082/ From: Sukhdev Kapur [mailto:sukhdevka...@gmail.com] Sent: Monday, March 10, 2014 5:56 PM To: Dane Leblanc (leblancd) Cc: OpenStack Development Mailing List (not for usage questions); openstack-in...@lists.openstack.org; openstack...@lists.openstack.org Subject: Re: [OpenStack-Infra] tgt restart fails in Cinder startup "start: job failed to start" I see the same issue. This issue has crept in during the latest flurry of check-ins. I started noticing this issue a day or two before the Icehouse Feature Freeze deadline. I tried restarting tgt as well, but, it does not help. However, rebooting the VM helps clear it up. Has anybody else seen it as well? Does anybody have a solution for it?
