[Condor-users] condor won't start after yum update

["Jack Fowler" <fowler@xxxxxxxxxxxxx>]

Hi,
 I updated condor to 7.4.4-1 and it now won't start with this error message in /var/log/condor/MasterLog :

11/05 11:05:30 FileLock::obtain(1) failed - errno 11 (Resource temporarily unavailable)
11/05 11:05:30 ERROR "Can't get lock on "/var/lock/condor/InstanceLock"" at line 956 in file master.cpp

Has anyone seen this before? 
Thanks, Jack
