Thanks Nat. The script didn't help but removing lock files from the directory that you mentioned definitely helped.<br><br>Thanks,<br>Salman<br><br><div><div id="SkyDrivePlaceholder"></div>> Date: Sat, 14 Apr 2012 21:55:47 -0400<br>> Subject: Re: [Openstack] nova-network service stuck<br>> From: nathanael.i.burton@gmail.com<br>> To: salmanmk@live.com<br>> CC: openstack@lists.launchpad.net<br>> <br>> Salman,<br>> <br>> The location for the locks is determined by the --lock_path setting in<br>> nova.conf.
